A 62-year-old client with dysphagia after a mild stroke is on a mechanical-soft diet with nectar-thick liquids. The client has a persistent cough when drinking and has consumed only 600 mL of fluids in 24 hours. Assessment: urine dark and concentrated, BP 110/66 mm Hg, HR 98/min. Labs: sodium 149 mEq/L. Which action should the nurse take FIRST to address the client's nutritional needs?

Request a speech-language pathology swallow re-evaluation and hold thin liquids until reassessed

Encourage the client to drink unthickened water between meals to increase hydration

Document the intake and reassess hydration status at the end of the shift

Delegate to assistive personnel to feed the client quickly to increase total intake

Explanation

This question tests clinical judgment in managing aspiration risk with inadequate hydration in dysphagia. The client shows signs of aspiration (persistent cough when drinking) despite prescribed texture modification, with resulting dehydration (dark concentrated urine, elevated sodium 149 mEq/L, inadequate fluid intake 600 mL/24 hours). Option A is correct because requesting swallow re-evaluation and holding thin liquids addresses the immediate safety concern of aspiration while ensuring appropriate texture modifications are determined to meet hydration needs safely. Option B is dangerous as it encourages unthickened liquids that are causing coughing/aspiration; Option C delays intervention for a client already showing dehydration; Option D increases aspiration risk by rushing feeding and is inappropriate delegation. The clinical principle is prioritizing airway protection while ensuring adequate hydration through appropriate texture modifications determined by expert swallow evaluation. In dysphagia management, always stop textures causing coughing/aspiration, request SLP re-evaluation for texture changes, consider alternative hydration methods if needed, and monitor for signs of both dehydration and aspiration pneumonia.

A 3-month-old infant is brought to the clinic with 1 day of diarrhea. The parent reports fewer wet diapers and difficulty feeding. Assessment: sunken anterior fontanel, dry mucous membranes, capillary refill 4 seconds, HR 168/min, weight decreased from 6.2 kg to 5.8 kg. What is the PRIORITY nursing intervention for this client's hydration status?

Teach the parent to dilute formula to provide additional free water

Initiate oral rehydration solution in small, frequent amounts and monitor for continued signs of dehydration

Collect a stool sample for culture before starting fluids

Delegate to assistive personnel to weigh diapers for output measurement

Explanation

This question tests clinical judgment in managing moderate to severe dehydration in an infant. The infant shows significant dehydration with 6.5% weight loss (0.4 kg loss from 6.2 kg), sunken fontanel, delayed capillary refill (4 seconds), and tachycardia (168/min), requiring immediate intervention to prevent shock. Option B is correct because initiating oral rehydration solution provides rapid, safe rehydration for infants who can tolerate oral fluids, with close monitoring for signs of worsening dehydration that would require IV therapy. Option A is dangerous as diluting formula reduces caloric density and electrolyte content, potentially causing hyponatremia; Option C delays treatment when clinical signs already indicate significant dehydration; Option D is helpful but not the priority intervention. The clinical principle is using oral rehydration therapy as first-line treatment for mild-moderate dehydration in infants who can tolerate oral intake, escalating to IV fluids if oral rehydration fails. When managing infant dehydration, calculate percent weight loss (>5% indicates moderate dehydration), start ORS at 50-100 mL/kg over 4 hours, and monitor for improvement in clinical signs or need for IV therapy.

3

A 33-year-old client is 12 hours post-operative after a bowel resection. The client has hypoactive bowel sounds, reports abdominal bloating, and has not passed flatus; IV fluids are infusing, and the client is NPO. Labs: glucose 102 mg/dL, Na 139 mEq/L, K 3.8 mEq/L. Which action should the nurse take FIRST to address the client's nutritional needs?

Advance the diet to a regular diet to prevent catabolism

Delegate to assistive personnel to provide a high-protein snack

Assess for return of bowel function by auscultating bowel sounds and asking about flatus before advancing diet

Obtain a prealbumin level to evaluate nutritional status

Explanation

This question tests clinical judgment in nutrition and hydration management. The priority concern is post-operative ileus preventing safe diet advancement, indicated by hypoactive bowel sounds, bloating, and no flatus. Assessing for return of bowel function before advancing the diet is the highest priority to prevent complications like aspiration or obstruction. Advancing to a regular diet, delegating a snack, or obtaining prealbumin are incorrect as they bypass necessary assessment or are premature. This applies the principle of prioritizing safety and physiological readiness in post-operative nutrition. A transferable strategy is to auscultate bowel sounds and confirm flatus passage routinely before progressing diets after GI surgery.

4

A 4-year-old child has a diagnosed peanut allergy and is admitted for asthma exacerbation. The child is underweight (BMI <5th percentile) and the parent reports the child "won't eat" in the hospital. Which dietary modification should the nurse implement IMMEDIATELY?

Encourage the child to eat only clear liquids until appetite improves

Offer high-protein peanut butter shakes to promote weight gain

Ensure all meals and snacks are peanut-free and verify ingredient lists before offering foods

Delegate food selection entirely to the parent without nurse verification

Explanation

This question tests clinical judgment in nutrition and hydration management. The priority concern is underweight status in a child with peanut allergy, compounded by hospital refusal to eat. Ensuring peanut-free meals and verifying ingredients is the highest priority to prevent anaphylaxis while promoting intake. Offering peanut butter, clear liquids, or delegating without verification are incorrect as they risk exposure or inadequate nutrition. This applies the principle of prioritizing allergen safety in pediatric nutrition. A transferable strategy is to collaborate with dietary services for safe, appealing options and involve parents in meal planning for allergic children.

5

A 47-year-old client is post-operative after gastric surgery and reports dumping symptoms (cramping and dizziness) after meals. The client has lost 3 kg in 1 month. Which dietary modification should the nurse implement IMMEDIATELY?

Encourage high-sugar beverages with meals to increase calories quickly

Teach the client to eat small, frequent meals and avoid drinking fluids with meals

Increase intake of very hot liquids to slow gastric emptying

Delegate teaching to dietary services and do not reinforce instructions

Explanation

This question tests clinical judgment in nutrition and hydration management. The priority concern is dumping syndrome causing symptoms and weight loss post-gastric surgery. Teaching small, frequent meals and avoiding fluids with meals is the highest priority to slow gastric emptying and improve tolerance. Encouraging high-sugar or hot liquids, or delegating without reinforcement are incorrect as they exacerbate symptoms. This applies the principle of symptom-specific dietary education for post-surgical complications. A transferable strategy is to instruct on meal separation from fluids and monitor weight in clients with dumping syndrome.

6

A 79-year-old client with mild dementia is admitted from an assisted living facility with confusion and weakness. The client has dry mucous membranes, poor skin turgor, and has had 300 mL of dark amber urine over the last 8 hours; vital signs: T 36.8°C (98.2°F), HR 108/min, BP 92/58 mm Hg, RR 18/min. Labs: Na 150 mEq/L, BUN 34 mg/dL, creatinine 1.2 mg/dL. What is the PRIORITY nursing intervention for this client's hydration status?

Initiate an IV line and begin isotonic fluids per facility protocol or provider order, then reassess vital signs and urine output

Request a dietitian consult to increase daily fluid intake goals

Delegate to assistive personnel to obtain a daily weight and record intake and output

Offer 120 mL (4 oz) of oral water every hour while awake

Explanation

This question tests clinical judgment in nutrition and hydration management. The priority concern is dehydration, evidenced by dry mucous membranes, poor skin turgor, low urine output, tachycardia, hypotension, hypernatremia, and elevated BUN/creatinine ratio. Initiating an IV line and administering isotonic fluids is the highest priority action to rapidly correct fluid volume deficit and improve perfusion in this elderly client with signs of severe dehydration. Offering oral water, requesting a dietitian consult, or delegating weights and I&O are lower priority as they do not address the immediate need for rehydration or require prior stabilization. This applies the principle of prioritizing ABCs and immediate interventions for life-threatening conditions like hypovolemia. A transferable strategy is to always assess hydration status using clinical signs and labs, then intervene promptly with IV fluids when oral intake is insufficient in vulnerable populations.

7

A 67-year-old client with heart failure is admitted with shortness of breath and edema. Current weight is 3 kg above baseline; lung sounds reveal crackles at bases. Labs: Na 132 mEq/L. The nurse should QUESTION which dietary order?

Daily weights at the same time each morning

Encourage 3 L/day of oral fluids to thin secretions

Fluid restriction 1.5 L/day

Low-sodium diet

Explanation

This question tests clinical judgment in nutrition and hydration management. The priority concern is fluid overload in heart failure, indicated by shortness of breath, edema, weight gain, and hyponatremia. The nurse should question encouraging 3 L/day of fluids as it could exacerbate congestion and dilutional hyponatremia. Fluid restriction, low-sodium diet, and daily weights are appropriate to monitor and manage volume status. This applies the principle of evaluating orders against clinical signs of overload. A transferable strategy is to tailor fluid goals based on cardiac function and symptoms, using weights and labs to guide adjustments in HF clients.

8

A 74-year-old client is receiving enteral feedings via NG tube after a stroke. The client has crackles at the right base and a new cough; gastric residual volume is 350 mL. Vital signs: T 37.9°C (100.2°F), RR 22/min. Which action should the nurse take FIRST to address the client's nutritional needs?

Document findings and reassess residual volume in 4 hours

Stop the feeding, elevate the head of bed, and assess for aspiration before resuming or notifying the provider

Delegate to assistive personnel to flush the tube and continue the feeding

Increase the feeding rate to meet caloric goals

Explanation

This question tests clinical judgment in nutrition and hydration management. The priority concern is potential aspiration in enteral feeding, evidenced by crackles, cough, fever, tachypnea, and high residual. Stopping the feeding, elevating HOB, and assessing for aspiration is the highest priority to protect the airway. Increasing rate, delegating flush, or documenting without action are incorrect as they risk further complications. This applies the principle of immediate intervention for life-threatening conditions like aspiration. A transferable strategy is to check residuals and lung sounds routinely, holding feedings and notifying providers if issues arise in tube-fed clients.

9

A 73-year-old client is admitted with dehydration after 2 days of vomiting. Assessment: sunken eyes, dry mucous membranes, and poor skin turgor; vital signs: HR 116/min, BP 88/54 mm Hg. Labs: Na 152 mEq/L, BUN 40 mg/dL, creatinine 1.4 mg/dL. What is the PRIORITY nursing intervention for this client's hydration status?

Start an IV and prepare to administer isotonic fluids per protocol or provider order, monitoring for improvement in perfusion

Encourage the client to drink 240 mL of water every 15 minutes

Provide education about avoiding spicy foods to reduce nausea

Delegate to assistive personnel to obtain a urine specimen for specific gravity

Explanation

This question tests clinical judgment in nutrition and hydration management. The priority concern is severe dehydration from vomiting, evidenced by sunken eyes, dry membranes, poor turgor, tachycardia, hypotension, hypernatremia, and elevated BUN/creatinine. Starting IV isotonic fluids is the highest priority to restore volume and perfusion rapidly. Encouraging large oral volumes, delegating urine tests, or educating on foods are incorrect as the client may not tolerate oral or needs immediate IV intervention. This applies the principle of prioritizing ABCs in hypovolemic states. A transferable strategy is to use IV rehydration for severe cases, monitoring labs and vital signs for response in dehydrated clients.

10

A 68-year-old client is post-operative day 2 after hip surgery and is receiving opioids for pain. The client reports constipation and poor appetite; intake has been <800 mL/day. Labs: Na 145 mEq/L, BUN 28 mg/dL. Which action should the nurse take FIRST to address the client's nutritional needs?

Keep the client NPO until the first bowel movement occurs

Delegate to assistive personnel to administer a PRN laxative without assessing the client

Encourage increased oral fluids and fiber as tolerated and promote early ambulation to support bowel function

Request an order for parenteral nutrition due to low intake

Explanation

This question tests clinical judgment in nutrition and hydration management. The priority concern is constipation and poor intake from opioids and low fluid/fiber, indicated by symptoms and mild dehydration labs. Encouraging fluids, fiber, and ambulation is the highest priority to promote bowel motility and hydration. Keeping NPO, delegating laxatives without assessment, or requesting PN are incorrect as they could worsen issues or are unnecessary. This applies the principle of non-pharmacologic interventions first for post-op complications. A transferable strategy is to integrate mobility and dietary fiber with hydration to prevent constipation in immobilized clients on opioids.
