1. A healthcare professional is reviewing the medical history of a client who has a new prescription for Metformin to treat type 2 diabetes. Which of the following findings should the healthcare professional report to the provider?
- A. Hemoglobin A1C of 7.5%
- B. Creatinine level of 1.2 mg/dL
- C. BUN level of 18 mg/dL
- D. Liver function tests showing AST of 50 units/L
Correct answer: D
Rationale: The correct answer is D. Elevated AST levels in liver function tests should be reported to the provider when a client is prescribed Metformin due to the potential risk of hepatotoxicity associated with the medication. Elevated Hemoglobin A1C (choice A), Creatinine level within normal range (choice B), and BUN level within normal range (choice C) are not directly concerning when initiating Metformin therapy.
2. A client has a new prescription for Nitroglycerin to treat angina. Which of the following instructions should the nurse include?
- A. Take this medication only when chest pain occurs.
- B. Store the medication in a cool, dry place.
- C. Apply the patch to a different site each time.
- D. Avoid consuming alcohol while taking this medication.
Correct answer: C
Rationale: The correct instruction for the nurse to include is to advise the client to apply the Nitroglycerin patch to a different site each time. This is crucial to prevent skin irritation and ensure consistent absorption of the medication. Rotating application sites is important as it helps maintain the effectiveness of the treatment and reduces the risk of skin reactions. Choice A is incorrect because Nitroglycerin is often used prophylactically to prevent angina episodes rather than just for acute chest pain. Choice B is not relevant to the administration or effectiveness of the medication. Choice D, while generally a good recommendation, is not directly related to the administration of Nitroglycerin.
3. A healthcare professional is educating a client who has a new prescription for Vitamin B12 injections. Which of the following statements should the healthcare professional include?
- A. Take the medication with a full glass of water.
- B. You will need to take this medication for the rest of your life.
- C. Expect a metallic taste in your mouth.
- D. Avoid consuming dairy products.
Correct answer: B
Rationale: The correct answer is B: 'You will need to take this medication for the rest of your life.' Clients with conditions like pernicious anemia or other causes of vitamin B12 deficiency may require lifelong cyanocobalamin supplementation to prevent deficiency. This is because their bodies are unable to absorb B12 from dietary sources adequately, necessitating ongoing injections to maintain optimal B12 levels. Choices A, C, and D are incorrect. A full glass of water is not necessary for Vitamin B12 injections. Metallic taste in the mouth is not a common side effect of Vitamin B12 injections, and there is no need to avoid consuming dairy products specifically in relation to Vitamin B12 injections.
4. To which pharmacologic classification does the drug propranolol belong?
- A. Beta Blockers
- B. Cholinergics
- C. Immune globulins
- D. Barbiturates
Correct answer: A
Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.
5. A client is receiving heparin therapy. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?
- A. PT
- B. aPTT
- C. INR
- D. Platelet count
Correct answer: B
Rationale: The corrected answer is B: aPTT. The activated partial thromboplastin time (aPTT) is the laboratory value used to monitor the effectiveness of heparin therapy. The aPTT should be maintained at 1.5 to 2 times the normal level to ensure therapeutic anticoagulation. Monitoring aPTT helps healthcare providers adjust heparin doses to achieve the desired anticoagulant effects and prevent complications such as bleeding or clotting. Choice A, PT (prothrombin time), is used to monitor warfarin therapy, not heparin. Choice C, INR (international normalized ratio), is also used to monitor warfarin therapy. Choice D, platelet count, is important for assessing the risk of bleeding, but it does not directly monitor the effectiveness of heparin therapy.
