1. Which electrolyte imbalance does the nurse suspect in a patient with hyperaldosteronism?
- A. Hyponatremia
- B. Hypernatremia
- C. Hyperkalemia
- D. Hypercalcemia
Correct answer: C
Rationale: In a patient with hyperaldosteronism, the nurse would suspect hyperkalemia. Hyperaldosteronism leads to increased potassium excretion, resulting in low potassium levels in the blood. Therefore, choices A (Hyponatremia), B (Hypernatremia), and D (Hypercalcemia) are incorrect. Hyponatremia refers to low sodium levels, Hypernatremia refers to high sodium levels, and Hypercalcemia refers to high calcium levels, none of which are typically associated with hyperaldosteronism.
2. When starting on oral contraceptives, what should the nurse emphasize about the potential interactions with other medications?
- A. Oral contraceptives can be less effective when taken with certain antibiotics.
- B. Oral contraceptives are less effective when taken with food.
- C. Oral contraceptives are effective immediately after starting.
- D. Oral contraceptives have no interactions with other medications.
Correct answer: A
Rationale: The correct answer is A. Oral contraceptives can be less effective when taken with certain antibiotics, so patients should be informed about the potential need for additional contraception. Choice B is incorrect because taking oral contraceptives with food does not affect their effectiveness. Choice C is incorrect because oral contraceptives may take some time to become fully effective. Choice D is incorrect because oral contraceptives can interact with other medications, especially certain antibiotics, affecting their efficacy.
3. A patient has been diagnosed with cytomegalovirus (CMV). Which of the following drugs would be ineffective in the treatment of this disease?
- A. Ribavirin (Rebetol)
- B. Ganciclovir (Cytovene) IV
- C. Foscarnet (Foscavir) IV
- D. Valganciclovir hydrochloride (Valcyte)
Correct answer: A
Rationale: The correct answer is A, Ribavirin (Rebetol). Ribavirin is not effective against CMV. Choice B, Ganciclovir (Cytovene) IV, is a common treatment for CMV as it inhibits viral DNA synthesis. Choice C, Foscarnet (Foscavir) IV, is also used for CMV infections by blocking viral DNA polymerase. Choice D, Valganciclovir hydrochloride (Valcyte), is a prodrug of Ganciclovir and is effective against CMV. Therefore, Ribavirin is the drug that would be ineffective in treating CMV.
4. The nurse is closely following a patient who began treatment with testosterone several months earlier. When assessing the patient for potential adverse effects of treatment, the nurse should prioritize which of the following assessments?
- A. Skin inspection for developing lesions
- B. Lung function testing
- C. Assessment of serum calcium levels
- D. Assessment of arterial blood gases
Correct answer: C
Rationale: In patients receiving testosterone therapy, the nurse should prioritize assessing serum calcium levels. Testosterone therapy can lead to hypercalcemia, making the evaluation of serum calcium levels crucial. Skin inspection for developing lesions, lung function testing, and arterial blood gas assessment are not the priority assessments for potential adverse effects of testosterone therapy. Skin inspection may be relevant for dermatological side effects, lung function testing and arterial blood gas assessment are not directly related to the common side effects of testosterone therapy.
5. A client has experienced a pontine stroke which has resulted in severe hemiparesis. What priority assessment should the nurse perform prior to allowing the client to eat or drink from the food tray?
- A. Evaluate the client's gag reflex.
- B. Assess the client's bowel sounds.
- C. Check the client's pupil reaction.
- D. Monitor the client's heart rate.
Correct answer: A
Rationale: The correct answer is to evaluate the client's gag reflex. When a client has experienced a stroke resulting in severe hemiparesis, assessing the gag reflex is crucial before allowing them to eat or drink. This assessment helps prevent aspiration, a serious complication that can occur due to impaired swallowing ability. Assessing bowel sounds (Choice B), pupil reaction (Choice C), or heart rate (Choice D) are important assessments but are not the priority in this situation where the risk of aspiration is higher.
