Nursing Elites

1. What is the primary action of insulin in the body?

• A. To lower blood pressure.
• B. To promote the absorption of glucose into cells.
• C. To increase blood glucose levels.
• D. To decrease blood glucose levels.

Correct answer: B

Rationale: The correct answer is B: To promote the absorption of glucose into cells. Insulin facilitates the uptake of glucose by cells, thereby decreasing blood glucose levels. Choice A is incorrect as insulin does not directly affect blood pressure. Choice C is inaccurate as insulin works to lower, not increase, blood glucose levels. Choice D is incorrect because insulin's primary role is to lower, not increase, blood glucose levels by promoting glucose uptake into cells.

2. A client with chronic kidney disease (CKD) is experiencing nausea, vomiting, visual changes, and anorexia. Which action by the nurse is best?

• A. Check the client’s digoxin (Lanoxin) level.
• B. Administer an anti-nausea medication.
• C. Ask if the client can eat crackers.
• D. Refer the client to a gastrointestinal specialist.

Correct answer: A

Rationale: In a client with chronic kidney disease experiencing symptoms like nausea, vomiting, visual changes, and anorexia, it is crucial for the nurse to suspect digoxin (Lanoxin) toxicity. These symptoms are indicative of digoxin toxicity. Therefore, the best action for the nurse to take is to check the client's digoxin level. Administering anti-nausea medication, asking about eating crackers, and referring to a gastrointestinal specialist may help with symptom management but do not address the underlying cause of the symptoms, which is digoxin toxicity in this case.

3. A client who is postmenopausal and has had two episodes of bacterial urethritis in the last 6 months asks, “I never have urinary tract infections. Why is this happening now?” How should the nurse respond?

• A. Your immune system becomes less effective as you age.
• B. Low estrogen levels can make the tissue more susceptible to infection.
• C. You should be more careful with your personal hygiene in this area.
• D. It is likely that you have an untreated sexually transmitted disease.

Correct answer: B

Rationale: Low estrogen levels in postmenopausal women decrease moisture and secretions in the perineal area, causing tissue changes that predispose them to infection, including urethritis. This is a common reason for urethritis in postmenopausal women. While immune function does decrease with aging and sexually transmitted diseases can cause urethritis, the most likely reason in this case is the low estrogen levels. Personal hygiene practices are usually not a significant factor in the development of urethritis.

4. The nurse is preparing to give a dose of a cephalosporin medication to a patient who has been receiving the antibiotic for 2 weeks. The nurse notes ulcers on the patient’s tongue and buccal mucosa. Which action will the nurse take?

• A. Hold the drug and notify the provider.
• B. Obtain an order to culture the oral lesions.
• C. Gather emergency equipment to prepare for anaphylaxis.
• D. Report a possible superinfection side effect of the cephalosporin.

Correct answer: D

Rationale: The nurse should report a possible superinfection side effect of the cephalosporin to the physician as the patient's symptoms may indicate a superinfection that requires treatment. Holding the drug is not necessary unless directed by the provider. Culturing the lesions is not indicated for this situation. There is no evidence to suggest impending anaphylaxis based on the patient's symptoms.

5. A client who is receiving chemotherapy asks the nurse, 'Why is so much of my hair falling out each day?' Which response by the nurse best explains the reason for alopecia?

• A. 'Chemotherapy affects the cells of the body that grow rapidly, both normal and malignant.'
• B. 'Alopecia is a common side effect you will experience during long-term steroid therapy.'
• C. 'Your hair will grow back completely after your course of chemotherapy is completed.'
• D. 'The chemotherapy causes permanent alterations in your hair follicles that lead to hair loss.'

Correct answer: A

Rationale: The correct answer is A: 'Chemotherapy affects the cells of the body that grow rapidly, both normal and malignant.' Chemotherapy targets rapidly dividing cells, which include not only cancer cells but also healthy cells like those in hair follicles. This leads to alopecia (hair loss) as a common side effect. Choice B is incorrect as alopecia is primarily associated with chemotherapy and not long-term steroid therapy. Choice C is incorrect because while hair may grow back after chemotherapy, it may not always be to the same extent or thickness. Choice D is incorrect as chemotherapy-induced hair loss is often temporary and reversible, not permanent alterations in hair follicles.
