1. A nurse is caring for a client with hypertension who asks about a prescription for propranolol. The nurse should inform the client that this medication is contraindicated in clients with a history of which of the following conditions?
- A. Asthma
- B. Glaucoma
- C. Depression
- D. Migraines
Correct answer: A
Rationale: Corrected Rationale: Propranolol is contraindicated in clients with a history of asthma because it can cause bronchospasms due to its non-selective beta-blocking properties. By blocking beta-2 receptors in the lungs, propranolol can lead to bronchoconstriction, potentially triggering asthma symptoms and exacerbating respiratory issues. Asthma patients should avoid medications like propranolol that can worsen their condition. Choices B, C, and D are incorrect as propranolol is not contraindicated in clients with glaucoma, depression, or migraines. In fact, propranolol is sometimes used in the treatment of migraines and certain types of glaucoma.
2. A healthcare professional is educating a client about the adverse effects of Metformin. Which of the following adverse effects should the healthcare professional include?
- A. Lactic acidosis.
- B. Hypoglycemia.
- C. Hyperlipidemia.
- D. Weight gain.
Correct answer: A
Rationale: The correct answer is A: Lactic acidosis. Lactic acidosis is a rare but severe side effect of Metformin, particularly in individuals with renal or liver issues. It is crucial for clients taking Metformin to be aware of the symptoms of lactic acidosis, such as muscle pain, weakness, trouble breathing, stomach discomfort, and feeling cold. Choice B, hypoglycemia, is not a common adverse effect of Metformin but can occur when combined with other antidiabetic medications. Choice C, hyperlipidemia, is not a typical adverse effect of Metformin. Choice D, weight gain, is not associated with Metformin use; in fact, Metformin is often associated with weight loss or weight neutrality.
3. A client has a new prescription for Losartan. Which of the following laboratory values should the nurse monitor?
- A. Serum potassium
- B. Serum sodium
- C. Serum calcium
- D. Serum magnesium
Correct answer: A
Rationale: Corrected Rationale: Losartan, an angiotensin II receptor blocker (ARB), can cause hyperkalemia. The nurse should monitor the client's serum potassium levels closely because Losartan can increase potassium levels, potentially leading to serious complications such as arrhythmias. Monitoring serum sodium, calcium, or magnesium levels is not typically necessary when a patient is prescribed Losartan, as these values are not directly affected by this medication.
4. A nurse reviewing a client's medical record notes a new prescription for verifying the trough level of the client's medication. Which of the following actions should the nurse take?
- A. Obtain a blood specimen immediately prior to administering the next dose of medication.
- B. Verify that the client has been taking the medication for 24 hours before obtaining a blood specimen.
- C. Ask the client to provide a urine specimen after the next dose of medication.
- D. Administer the medication and obtain a blood specimen 30 minutes later.
Correct answer: A
Rationale: To verify the trough levels of a medication accurately, the nurse should obtain a blood specimen immediately before administering the next dose of the medication. The trough level represents the lowest concentration of the medication in the bloodstream, typically right before the next dose is due. This timing ensures an accurate assessment of the drug's concentration in the body at its lowest point, aiding in determining the drug's effectiveness and potential toxicity levels. Choice B is incorrect because waiting for 24 hours would not provide the trough level. Choice C is incorrect as urine specimens are not used to measure trough levels. Choice D is incorrect as obtaining a blood specimen 30 minutes after administering the medication would not reflect the trough level.
5. A client is taking Epoetin Alfa for anemia. Which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?
- A. White blood cell count
- B. Platelet count
- C. Hematocrit
- D. Serum potassium level
Correct answer: C
Rationale: The nurse should monitor the hematocrit level to evaluate the effectiveness of Epoetin Alfa therapy. Epoetin Alfa stimulates red blood cell production, leading to an increase in hematocrit levels. Monitoring the hematocrit helps assess the response to therapy and ensures that the medication is effectively addressing the anemia. White blood cell count and platelet count are not directly affected by Epoetin Alfa therapy. Serum potassium level monitoring is important for other medications that may impact potassium levels but is not specifically relevant to assessing the effectiveness of Epoetin Alfa in treating anemia.
