1. 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.
2. What is the correct definition of drug absorption?
- A. Movement of a drug from the site of administration to various tissues of the body
- B. Describes the absorption, distribution, metabolism, and excretion of drugs
- C. These types of drugs can be taken over the counter
- D. This addresses how various drugs affect different forms of the body
Correct answer: A
Rationale: The correct definition of drug absorption is the movement of a drug from the site of administration into various tissues of the body. It is the process by which a drug is taken up and enters the systemic circulation. Choice B describes the pharmacokinetics of drugs, including absorption, distribution, metabolism, and excretion, but it is not a specific definition of drug absorption. Choice C is unrelated to drug absorption, as it refers to over-the-counter drugs. Choice D is too vague and does not specifically address the process of drug absorption.
3. A client is prescribed Metformin. Which of the following laboratory values should be monitored to assess for potential adverse effects?
- A. Blood glucose
- B. Creatine kinase
- C. Hemoglobin A1c
- D. Serum creatinine
Correct answer: D
Rationale: The correct answer is D: Serum creatinine. Metformin can potentially cause lactic acidosis, particularly in patients with impaired renal function. Monitoring serum creatinine levels is crucial to assess kidney function and detect any adverse effects of Metformin on renal health. Choices A, B, and C are incorrect as blood glucose, creatine kinase, and hemoglobin A1c levels are not directly monitored to assess for potential adverse effects of Metformin. Blood glucose monitoring is typically done to assess the efficacy of antidiabetic medications like Metformin, while creatine kinase levels are indicative of muscle damage and hemoglobin A1c reflects long-term blood sugar control.
4. A client has a new prescription for Valsartan, and a nurse is providing discharge teaching. Which of the following instructions should the nurse include?
- A. Take this medication with food.
- B. Avoid potassium-rich foods.
- C. Expect to feel drowsy.
- D. Monitor your blood pressure daily.
Correct answer: D
Rationale: Monitoring blood pressure daily is crucial for clients taking Valsartan, an angiotensin II receptor blocker, to ensure effective management of hypertension. Valsartan helps lower blood pressure by relaxing blood vessels, and regular monitoring helps track the medication's effectiveness and any potential side effects. Choices A, B, and C are incorrect because Valsartan does not need to be taken with food, avoiding potassium-rich foods is not specifically required for this medication, and feeling drowsy is not a common side effect of Valsartan.
5. When teaching parents about a child newly prescribed Desipramine, the nurse should instruct them that which of the following adverse effects is the priority to report to the provider?
- A. Constipation
- B. Suicidal thoughts
- C. Photophobia
- D. Dry mouth
Correct answer: B
Rationale: The priority adverse effect to report when a child is prescribed Desipramine is suicidal thoughts. Desipramine can increase the risk of suicidal thoughts and behaviors. It is crucial for parents to monitor the child for any signs of worsening depression or thoughts of self-harm and report them promptly to the healthcare provider to prevent any harm to the child. Options A, C, and D are potential side effects of Desipramine but are not as urgent or life-threatening as suicidal thoughts, which require immediate intervention to ensure the safety of the child.
