1. A patient who is taking a potassium-wasting diuretic for the treatment of hypertension complains of generalized weakness. It is most appropriate for the nurse to take which action?
- A. Assess for facial muscle spasms.
- B. Ask the patient about loose stools.
- C. Suggest that the patient avoid orange juice with meals.
- D. Ask the healthcare provider to order a basic metabolic panel.
Correct answer: D
Rationale: Generalized weakness is a sign of hypokalemia, a potential side effect of potassium-wasting diuretics. By requesting a basic metabolic panel, the nurse can assess the patient's potassium levels. Facial muscle spasms are associated with hypocalcemia, not hypokalemia. Advising the patient to avoid orange juice, which is high in potassium, would be counterproductive if the patient is hypokalemic. Loose stools are typically seen in hyperkalemia, not hypokalemia.
2. A client who received multiple antihypertensive medications experiences syncope due to a drop in blood pressure to 70/40. What is the rationale for the nurse's decision to hold the client's scheduled antihypertensive medication?
- A. Increased urinary clearance of the multiple medications has produced diuresis and lowered the blood pressure
- B. The antagonistic interaction among the various blood pressure medications has reduced their effectiveness
- C. The additive effect of multiple medications has caused the blood pressure to drop too low.
- D. The synergistic effect of the multiple medications has resulted in drug toxicity and resulting hypotension.
Correct answer: C
Rationale: When medications with a similar action are administered, an additive effect occurs that is the sum of the effects of each medication. In this case, several medications that all lower blood pressure, when administered together, resulted in hypotension.
3. During the infusion of a second unit of packed red blood cells, the client's temperature increases from 99 to 101.6 F. Which intervention should the nurse implement?
- A. Stop the transfusion and start a saline infusion.
- B. Administer antipyretics and continue the transfusion.
- C. Monitor the client’s vital signs every 15 minutes.
- D. Notify the healthcare provider and continue the transfusion.
Correct answer: A
Rationale: An increase in temperature during a transfusion may indicate a transfusion reaction, which can be serious. Stopping the transfusion and starting a saline infusion is the priority action to prevent further complications and address the potential adverse reaction. Administering antipyretics (choice B) may mask the symptoms of a transfusion reaction, delaying appropriate treatment. While monitoring vital signs (choice C) is important, stopping the transfusion takes precedence to prevent harm. Notifying the healthcare provider (choice D) is essential but should not delay the immediate intervention of stopping the transfusion and starting a saline infusion.
4. After a myocardial infarction, a client is placed on a sodium-restricted diet. When the nurse is teaching the client about the diet, which meal plan would be the most appropriate?
- A. 3 oz. broiled fish, 1 baked potato, 1/2 cup canned beets, 1 orange, and milk
- B. 3 oz. canned salmon, fresh broccoli, 1 biscuit, tea, and 1 apple
- C. A bologna sandwich, fresh eggplant, 2 oz fresh fruit, tea, and apple juice
- D. 3 oz. turkey, 1 fresh sweet potato, 1/2 cup fresh green beans, milk, and 1 orange
Correct answer: D
Rationale: The correct answer is D. A meal of turkey, sweet potato, green beans, milk, and an orange is low in sodium and suitable for a post-MI diet. Choice A includes a baked potato and canned beets, which are higher in sodium. Choice B includes canned salmon, which can be high in sodium. Choice C includes a bologna sandwich, which is also high in sodium compared to the other options.
5. Capillary glucose monitoring is being performed every 4 hours for a female client diagnosed with diabetic ketoacidosis. Insulin is administered using a scale of regular insulin according to glucose results. At 2 p.m., the client has a capillary glucose level of 250 mg/dl for which she receives 8 U of regular insulin. Nurse Vince should expect the dose's:
- A. Onset to be at 2 p.m. and its peak to be at 3 p.m.
- B. Onset to be at 2:15 p.m. and its peak to be at 3 p.m.
- C. Onset to be at 2:30 p.m. and its peak to be at 4 p.m.
- D. Onset to be at 4 p.m. and its peak to be at 6 p.m.
Correct answer: C
Rationale: The correct answer is C. Regular insulin typically has an onset of action within 30 minutes and peaks 2-4 hours after administration. Given that the insulin was administered at 2 p.m., the onset of action can be expected around 2:30 p.m., and the peak effect would occur between 4-6 p.m. Choice A is incorrect as the onset and peak are too close together for regular insulin. Choice B is incorrect because the onset time is too soon after administration. Choice D is incorrect as the onset time is too delayed for regular insulin.
