Nutrition And Oral Hydration - NCLEX Pn

1. After feeding a patient at aspiration risk, how long should the patient remain upright?

   At least $30\ \text{minutes}$. Maintaining position post-meal prevents reflux and aspiration by allowing time for gastric emptying.

2. Which sign during meals indicates possible aspiration and requires stopping feeding?

   Coughing or wet/gurgly voice while swallowing. These indicate material entering airways, signaling aspiration risk that requires immediate intervention to protect lungs.

3. Which diet order is appropriate for a patient with difficulty chewing due to poor dentition?

   Mechanical soft diet. Soft textures ease mastication for those with dental issues, promoting safe and adequate nutritional intake.

4. Calculate total intake: water $240\ \text{mL}$ + soup $180\ \text{mL}$ + gelatin $120\ \text{mL}$. What is total?

   $540\ \text{mL}$. Summing liquid volumes provides total intake for accurate fluid balance assessment in patient care.

5. Which consistency is safest for many patients with dysphagia to reduce aspiration risk?

   Thickened liquids (e.g., nectar or honey thick as prescribed). Thicker fluids move slower, allowing better swallow control and reducing chance of entering airways in dysphagia.

6. A patient gains $2\ \text{kg}$ in $24\ \text{hr}$. Approximately how much fluid is retained?

   About $2\ \text{L}$ retained. Weight gain reflects fluid retention, with each kilogram approximating one liter in acute settings.

7. What is the standard daily fluid intake goal for a healthy adult, unless contraindicated?

   About $2000\text{ to }3000\ \text{mL/day}$ (about $2\text{ to }3\ \text{L/day}$). Adequate hydration maintains fluid balance, electrolyte levels, and organ function in healthy adults without restrictions.

8. Which diet is typically prescribed for a patient with celiac disease to prevent symptoms?

   Gluten-free diet. Avoiding gluten prevents intestinal damage and malabsorption in celiac disease, controlling symptoms effectively.

9. Which nutrient is most directly required for collagen formation and wound healing support?

   Vitamin C. It acts as a cofactor in collagen synthesis, enhancing wound strength and tissue repair mechanisms.

10. What is the primary nursing action before offering oral fluids to a patient with dysphagia?

    Assess swallowing ability (speech/swallow evaluation as ordered). Evaluation prevents aspiration by identifying swallow impairments, ensuring safe oral intake for at-risk patients.

11. What is the priority nursing action when a patient reports food allergy symptoms after eating?

    Stop the food and assess airway and breathing immediately. Immediate cessation and assessment prevent progression to anaphylaxis by addressing potential airway compromise.

12. Calculate fluid balance: intake $1500\ \text{mL}$ and output $1100\ \text{mL}$. What is the balance?

    Positive $400\ \text{mL}$. Subtracting output from intake determines net balance, indicating retention or deficit for clinical management.

13. What weight change corresponds to approximately $1\ \text{L}$ of fluid gain or loss?

    $1\ \text{kg}$ (about $2.2\ \text{lb}$). Body fluid density approximates water, so gains or losses manifest as equivalent weight changes in short periods.

14. Identify the best method to measure oral intake accurately for intake and output documentation.

    Measure in mL using calibrated containers; record actual consumed amount. Precise measurement ensures accurate tracking of fluid balance, critical for monitoring hydration and health status.

15. Which laboratory value is most directly used to evaluate hydration status and water balance?

    Serum osmolality. It measures solute concentration in blood, reflecting water balance and hydration more precisely than other electrolytes.

16. What is the most reliable clinical indicator of fluid balance change in a hospitalized patient?

    Daily weight on the same scale and time. Consistent measurements detect subtle fluid shifts accurately, as weight changes correlate directly with fluid balance.

17. What is the correct positioning for oral feeding to reduce aspiration risk?

    High Fowler position, upright $90^\circ$ if possible. Upright positioning uses gravity to direct food downward, minimizing reflux and aspiration during swallowing.

18. Which electrolyte abnormality is most associated with muscle weakness and dysrhythmias in poor intake?

    Hypokalemia. Low potassium from inadequate intake disrupts muscle and cardiac cell function, leading to weakness and irregular rhythms.

19. What is the best first nursing intervention to promote oral intake in a nauseated patient?

    Offer small, frequent sips or meals and avoid strong odors. Small amounts reduce gastric overload, while avoiding odors minimizes nausea triggers to encourage better intake.

20. Which diet is appropriate when a patient needs increased calories and protein for wound healing?

    High-calorie, high-protein diet. Increased nutrients support tissue repair, immune function, and energy needs during healing processes.

21. Which assessment finding most strongly suggests fluid volume overload?

    New crackles with rapid weight gain. Excess fluid leads to pulmonary edema, causing crackles, while rapid weight gain reflects volume overload in the body.

22. Identify the earliest clinical sign of dehydration commonly noted in older adults.

    Acute confusion or change in mental status. Older adults may show neurological changes first due to brain sensitivity to fluid imbalances before physical signs appear.

23. What is the minimum urine output that generally indicates adequate kidney perfusion in adults?

    At least $30\ \text{mL/hr}$. This level ensures kidneys are filtering blood effectively, preventing waste buildup and indicating sufficient perfusion.

24. Which urine specific gravity finding is most consistent with dehydration?

    Elevated urine specific gravity (concentrated urine). Dehydration reduces water in urine, increasing concentration and specific gravity above normal ranges like 1.010-1.025.

25. Which diet is appropriate immediately after surgery when bowel sounds are present but intake is limited?

    Clear liquid diet. Clear liquids are easily digested, providing hydration while minimizing gastrointestinal stress post-operatively.
