Eye lubricants are used for all but the following:
To achieve miosis during eye surgery
To replace tears or add moisture to eyes
To protect the eyes during surgery or diagnostic procedures
To moisten contact lenses or artificial eyes
Eye lubricants are not used to achieve miosis during eye surgery. Eye lubricants are frequently used to treat dry eyes in cases where tears need to be replaced, to moisten contact lenses, or to protect eyes during surgery.
You are a nurse in an emergency department and a patient presents with a 5 cm by 6 cm abscess on the dorsal aspect of his left hand. The hand is very painful, but he has full range of motion, and no sensory deficits. He is afebrile and has no systemic or localized symptoms aside from the abscess. Which of the following is the most appropriate next step in management?
Incision and drainage of the abscess
Prescribe oral antibiotics without draining the abscess
Amputate the affected hand at the wrist
Inject steroid into the abscess
Apply topical antibiotic to the abscess
The correct answer is "incision and drainage of the abscess." This is the correct answer, because an abscess, by definition, is a walled off collection of pus and bacteria, that is typically impenetrable to topical or systemic antibiotics. The only way to truly resolve an abscess is to incise and drain it, such that the walled off material can be expelled, and the pressure and pain can be relieved. Further, the material should be sent for culture so that the patient can be placed on appropriate antibiotics if the physician deems it necessary for post-drainage care.
The other choices are incorrect. Surgical amputation of the affected hand would be a drastic measure for a localized abscess that is not otherwise causing limb ischemia or necrosis. Incision and drainage is a much more reasonable first step. Injecting a steroid into the abscess would be a potentially dangerous intervention as steroids decrease the body's immune response to infection, and as such, could increase the bacterial load within the abscess, allowing it to expand and become more serious. As mentioned earlier, topical and oral antibiotics would likely be impenetrable to the abscess and would be inappropriate first steps when the option of incision and drainage exists.
The community health nurse educates a group of young boys who are learning about hiking safety. Which of the following statements made by the nurse is not effective for preventing Lyme disease?
“You can take antibiotic medications before hiking to make sure you don’t get Lyme disease.”
“You should wear insect repellant on your skin and clothes if you are in an area endemic to Lyme disease.”
“Try to cover as much of your skin as possible - long pants, long sleeves, long socks, and cover your neck and hands too.”
“After you hike in a Lyme disease-endemic area, carefully examine your skin for ticks.”
“You should be aware of where ticks infected with Lyme disease are located, particularly in the upper Midwest, New England, and the mid-Atlantic region.”
Prophylactic antibiotics are not indicated for the prevention of Lyme disease. Antibiotics will be used after a tick bite when symptoms develop and an infection is suspected. The community health nurse should teach rules of prevention, including 1) knowing where Lyme disease is prevalent (New England, upper Midwest, mid-Atlantic states), 2) wearing long sleeves and long pants, covering as much skin as possible with clothing, 3) using insect repellant such as sprays over the whole body, and 4) checking for tick bites especially after exposure is anticipated, so you may receive care as quickly as possible if needed.
Which of the following bodily fluids does not transmit human immunodeficiency virus (HIV)?
Saliva
Blood
Breast milk
Vaginal secretions
Semen
HIV is easily spread through all of the listed body fluids with the exception of saliva. A person may not contract HIV through exchange of saliva during activities such as kissing or sharing eating utensils.
Which of the following is considered to be a normal age-related ocular degeneration?
Presbyopia
Glaucoma
Blepharitis
Cataracts
Presbyopia, or farsightedness, is caused by a loss of elasticity in the lens of the eye, and is considered a normal change with aging.
Glaucoma, blepharitis, and cataracts all carry increased risk with advanced age, but are considered to be abnormal and/or pathological changes.
Which of the following is part of a standard treatment plan for a diagnosis of stage I Lyme disease?
A topical antihistamine to reduce symptoms
No treatment unless the disease progresses to stage II or stage III
Administration of oral antibiotics
Administration of intravenous antibiotics
Stage 1 is called early localized Lyme disease. The infection is not yet widespread throughout the body. This is treated with a topical antihistamine to reduce symptoms.
A nurse is looking over a basic metabolic panel for a 69 year old male. She notices that his BUN is . This value is __________.
normal
elevated
depressed
borderline elevated
BUN, or blood urea nitrogen, is a measurement of the kidney's ability to excrete urea, which is a byproduct of protein metabolism. This patient's BUN is within normal range: the reference range for BUN is .
You are the nurse taking care of an elderly patient with severe dementia and limited mobility who is at a high risk for developing a pressure ulcer. Which of the following options is the best first-line approach to preventing development of a pressure ulcer in this patient?
Turning the patient multiple times per day
Applying topical antibiotic ointment to cover the patient's entire body surface
Administering broad-spectrum intravenous antibiotics
Request a dermatology consult
Administer a one time dose of broad spectrum intramuscular antibiotics
The correct answer is "Turning the patient multiple times per day." This is the correct answer because in the preventive stage for pressure ulcer management, there is no need to perform any invasive procedures, administer antibiotics in a patient who may be at high-risk for needing broad-spectrum antibiotics in the future (hence fostering antibiotic resistance), or consult subspecialty services (as there is no dermatological condition to be treated at the moment). The best option to prevent a pressure ulcer in a patient who is at high risk for developing a pressure ulcer is to turn the patient regularly while they are in bed, if they are bed-bound. By turning the patient, the high-pressure areas that would be at the highest risk for development of a pressure ulcer are able to have relief from pressure for a greater proportion of the day/night, and as such, can have blood flow restored while the patient is turned. By allowing for maximal blood flow to these regions, the risk of ischemia and subsequent infection and/or ulcer development is decreased. Without the actual development of an ulcer or infection, administering antibiotics, either topically, intramuscularly, or intravenously is inappropriate.
Which of the following is not a risk factor for infertility in men?
Mild sun exposure
Moderate cigarette smoking
Major hernia surgery
Untreated chlamydia
Frequent spa use
Cigarette smoking and other poor lifestyle choices have been shown to cause decreased fertility in men. Surgeries such as hernia repair can also have a negative effect on male fertility. Sexually transmitted infection can cause fertility problems, especially if left untreated, in males and females. Frequent hot tub or spa use has also not recommended. Mild levels of sun exposure are the least likely of the above to cause infertility in men.
The nurse is educating a 19-year-old female on contraceptive methods. The nurse describes which of these as the most effective?
The male condom
The female condom
A diaphragm and spermicide
Withdrawal before ejaculation
Fertility awareness
The male condom is the most effective when used correctly. However, if used incorrectly, carries a much higher risk of failure. The male condom is also the only method of the answer choices that also carries protection against sexually transmitted diseases.
