Which of the following lab values should the nurse monitor for a patient receiving heparin therapy?

Correct Answer: C

Rationale: The correct answer is to monitor aPTT for a patient receiving heparin therapy. The activated partial thromboplastin time (aPTT) is used to assess and adjust heparin dosage to ensure the patient is within the therapeutic range for anticoagulation. Monitoring the aPTT helps in preventing both clotting and bleeding complications. Platelet count (Choice A) is important to monitor for patients receiving antiplatelet therapy, not heparin. PT/INR (Choice B) is typically monitored for patients on warfarin therapy, not heparin. Monitoring the complete blood count (CBC) (Choice D) is essential for various conditions but is not specific to monitoring heparin therapy.

Correct Answer: B

Rationale: When administering opioids, monitoring the respiratory rate is crucial to detect any signs of respiratory depression, which is a serious side effect of opioid use. Monitoring blood pressure, heart rate, and oxygen saturation are important parameters to assess a patient's overall condition, but they are not the primary focus when administering opioids.

Correct Answer: A

Rationale: The correct answer is A: 'To reduce nausea and vomiting.' Antiemetics are medications used to prevent or alleviate nausea and vomiting. While they may indirectly help with appetite by reducing the unpleasant symptoms that can lead to decreased food intake, their primary purpose is not to increase appetite (Choice B). Choice C, 'To treat nausea caused by chemotherapy,' is partly correct as antiemetics are commonly used to manage chemotherapy-induced nausea, but this is not their exclusive purpose. Choice D, 'To treat allergic reactions,' is incorrect as antiemetics are not primarily used for treating allergic reactions.

Correct Answer: B

Rationale: Providing oral glucose is the correct intervention for a patient experiencing hypoglycemia. Oral glucose helps quickly raise blood sugar levels, making it the preferred treatment for mild hypoglycemia. Administering glucagon (Choice A) is usually reserved for severe cases when the patient cannot take anything by mouth. Administering IV fluids (Choice C) is not the primary intervention for hypoglycemia unless the patient is severely dehydrated. Monitoring blood sugar levels (Choice D) is important but providing glucose is the immediate priority to treat hypoglycemia.

Correct Answer: A

Rationale: The correct answer is to monitor serum creatinine. In patients with chronic kidney disease, monitoring serum creatinine is crucial as it reflects kidney function. This assessment helps healthcare providers in evaluating the progression of the disease and adjusting treatment plans accordingly. Monitoring blood pressure (choice B) is essential in managing chronic kidney disease, but monitoring serum creatinine takes precedence. Monitoring urine output (choice C) and potassium levels (choice D) are also important aspects of managing chronic kidney disease, but they are not the priority assessment compared to monitoring serum creatinine.
