A patient who is receiving chemotherapy for breast cancer develops thrombocytopenia. What should the nurse include in the care plan?

Correct Answer: B

Rationale: The correct answer is B: Avoid intramuscular injections. Thrombocytopenia is a condition characterized by low platelet count, which can lead to impaired blood clotting. Intramuscular injections can cause bleeding and bruising due to the decreased ability of blood to clot. Therefore, it is crucial to avoid invasive procedures like intramuscular injections to prevent excessive bleeding in patients with thrombocytopenia. Encouraging light exercise (choice A) can be beneficial for overall health but may not directly address the risk of bleeding. Avoiding aspirin (choice C) is important as it can further increase the risk of bleeding. Using a soft toothbrush for oral care (choice D) is a good practice, but it does not directly address the risk associated with intramuscular injections in patients with thrombocytopenia.

Correct Answer: C

Rationale: Rationale: C is correct because thiazide diuretics can cause fluid retention, leading to weight gain, which may indicate worsening heart failure or hypertension. Daily weight monitoring helps detect fluid retention early, enabling timely intervention. Summary: A: Incorrect. Thiazide diuretics can cause potassium loss, so avoiding potassium-rich foods is not necessary. B: Incorrect. Taking the medication in the morning is preferred to prevent nocturia and sleep disturbances. D: Incorrect. Fluid intake should not be limited unless advised by a healthcare provider to prevent dehydration.

Correct Answer: A

Rationale: The correct answer is A: Have the patient void immediately before the procedure. This step is crucial to prevent accidental puncture of the bladder during paracentesis. Voiding helps empty the bladder, reducing the risk of injury and ensuring a safer procedure. Incorrect choices: B: Position the patient flat in bed - Incorrect, as the patient should be in a sitting position with legs dangling over the side of the bed during the procedure. C: Administer a full liquid diet - Incorrect, as a full liquid diet is not necessary for paracentesis preparation. D: Encourage the patient to ambulate for 30 minutes - Incorrect, as ambulation is not relevant to preparing for paracentesis.

Correct Answer: B

Rationale: The correct answer is B: Take the medication in the morning on an empty stomach. Levothyroxine should be taken on an empty stomach, preferably 30 minutes to 1 hour before breakfast, to ensure optimal absorption. Food can interfere with absorption, so taking it with meals (choice A) is not recommended. Discontinuing the medication if feeling better (choice C) is dangerous as it can lead to a relapse of hypothyroidism. Doubling the dose if a dose is missed (choice D) can result in overdose and adverse effects. Therefore, choice B is the best option for optimal effectiveness of levothyroxine therapy.

Correct Answer: C

Rationale: The primary reason for administering morphine to a patient with MI is to reduce cardiac workload. Morphine acts as a vasodilator and decreases preload and afterload on the heart, reducing myocardial oxygen demand. This helps to improve coronary blood flow and decrease the workload on the heart muscle, which is crucial in the setting of an MI. Explanation for other choices: A: While morphine can help reduce pain in MI, the primary reason for administering it is to reduce cardiac workload. B: Morphine may have a calming effect, but the primary goal is to reduce cardiac workload. D: Morphine can actually decrease respiratory rate as a side effect, making this choice incorrect.
