1. Which of the following nursing diagnoses would provide the most plausible indication for the use of epoetin alfa (Epogen) in a patient with renal failure?
- A. Risk for infection related to decreased erythropoiesis
- B. Activity intolerance related to decreased oxygen-carrying capacity
- C. Powerlessness related to sequelae of renal failure
- D. Ineffective breathing pattern related to inadequate erythropoietin synthesis
Correct answer: B
Rationale: The correct answer is B. In a patient with renal failure, the use of epoetin alfa (Epogen) is primarily aimed at addressing the decreased oxygen-carrying capacity due to impaired erythropoiesis. Epoetin alfa is a medication that stimulates red blood cell production, thereby improving the oxygen-carrying capacity of the blood. This would directly address the activity intolerance commonly seen in patients with renal failure. Choices A, C, and D are incorrect because they do not directly relate to the primary purpose of using epoetin alfa in this context. Risk for infection, powerlessness, and ineffective breathing pattern are important considerations in the care of a patient with renal failure, but they are not the primary indications for using epoetin alfa.
2. A patient is prescribed estradiol (Estrace) for hormone replacement therapy. What should the nurse monitor during this therapy?
- A. Blood pressure
- B. Blood glucose levels
- C. Liver function tests
- D. Kidney function tests
Correct answer: C
Rationale: During estradiol therapy, the nurse should monitor liver function tests. Estradiol can potentially impact liver function, making it essential to assess for any signs of liver dysfunction. Monitoring blood pressure (Choice A) is not directly related to estradiol therapy. While blood glucose levels (Choice B) should be monitored in patients taking certain medications like corticosteroids or antipsychotics, it is not typically necessary for patients on estradiol therapy. Kidney function tests (Choice D) are not the priority for monitoring during estradiol therapy, as the liver is more commonly affected.
3. Which of the following statements describes an active cellular membrane exchange process?
- A. Sodium moving out of cells and potassium moving into cells
- B. The movement of water from an area of low solute concentration to an area of high solute concentration
- C. The movement of insulin using a protein to travel across the cell membrane
- D. Oxygen moving across the pulmonary capillaries to an area of high carbon dioxide
Correct answer: A
Rationale: The correct answer is A. In active transport, energy is expended to move substances against their concentration gradient. Sodium moving out of cells and potassium moving into cells is an example of active transport because it requires energy to pump these ions across the cell membrane against their concentration gradients. Choices B, C, and D describe passive processes where substances move along their concentration gradients without the input of energy.
4. A patient is prescribed sildenafil (Viagra) for erectile dysfunction. What key contraindication should the nurse review with the patient?
- A. Use of nitrates
- B. History of hypertension
- C. Use of antihypertensive medications
- D. Use of antihypertensive medications
Correct answer: A
Rationale: The correct answer is A: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, so their combined use can lead to a dangerous drop in blood pressure. Choices B, C, and D are incorrect because while a history of hypertension or use of antihypertensive medications may influence treatment decisions, they are not the key contraindication specifically related to sildenafil use.
5. A patient is being treated with hormone replacement therapy (HRT) for menopausal symptoms. What are the risks associated with long-term HRT that the nurse should discuss with the patient?
- A. HRT may increase the risk of cardiovascular events and breast cancer.
- B. HRT may decrease the risk of osteoporosis.
- C. HRT may increase the risk of venous thromboembolism.
- D. HRT may improve mood and energy levels.
Correct answer: A
Rationale: The correct answer is A. Long-term HRT is associated with increased risks of cardiovascular events and breast cancer. These risks should be discussed with the patient to ensure they are informed about the potential adverse effects. Choice B is incorrect because HRT does not decrease the risk of osteoporosis; in fact, it may increase the risk of certain conditions like cardiovascular events. Choice C is incorrect as HRT is associated with an increased risk of venous thromboembolism, not a decreased risk. Choice D is incorrect because while HRT may have positive effects like improving symptoms of menopause, it is not primarily indicated for improving mood and energy levels.
