1. What is the most important nursing intervention for a patient with increased intracranial pressure (ICP)?
- A. Elevate the head of the bed to 30 degrees.
- B. Administer diuretics to reduce fluid volume.
- C. Administer corticosteroids to reduce inflammation.
- D. Keep the patient in a supine position.
Correct answer: A
Rationale: Elevating the head of the bed to 30 degrees is crucial for a patient with increased intracranial pressure (ICP) because it helps promote venous drainage from the brain, thereby reducing ICP. Keeping the head of the bed elevated helps facilitate cerebral perfusion and can prevent a further increase in ICP. Administering diuretics (Choice B) may be considered in some cases to reduce fluid volume, but it is not the most critical intervention for immediate ICP management. Administering corticosteroids (Choice C) is not typically indicated for managing increased ICP unless there is a specific underlying condition requiring their use. Keeping the patient in a supine position (Choice D) can actually worsen ICP by impeding venous outflow from the brain, making it an incorrect choice for this scenario.
2. A child who weighs 10 kg will begin taking oral trimethoprim-sulfamethoxazole (TMP-SMX). The liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL. The nurse determines that the child’s dose should be 8 mg of TMP and 40 mg of SMX/kg/day divided into two doses. Which order for this child is correct?
- A. 5 mL PO BID
- B. 5 mL PO daily
- C. 10 mL PO BID
- D. 10 mL PO daily
Correct answer: A
Rationale: The correct answer is A: '5 mL PO BID.' To calculate the child’s daily dose requirement, you multiply the child's weight (10 kg) by the prescribed dosage per kg, which is 8 mg for TMP and 40 mg for SMX. This results in a total daily requirement of 80 mg of TMP and 400 mg of SMX. To divide this into two doses, each dose should contain half of the total daily requirement, which is 40 mg TMP and 200 mg SMX. Since the liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL, the correct dose per administration is 5 mL. Therefore, 5 mL PO BID is the correct order. Choice B, '5 mL PO daily,' is incorrect as the total daily dose needs to be divided into two doses. Choices C and D, '10 mL PO BID' and '10 mL PO daily,' respectively, are incorrect as they do not align with the calculated dosage requirements based on the child's weight and the prescribed dosage per kg.
3. The client with diabetes mellitus should be cautioned by the nurse taking a sulfonylurea that alcoholic beverages should be avoided while taking these drugs because they can cause which of the following?
- A. Hypokalemia.
- B. Hyperkalemia.
- C. Hypocalcemia.
- D. Disulfiram (Antabuse)-like symptoms.
Correct answer: D
Rationale: The correct answer is D: Disulfiram (Antabuse)-like symptoms. When a client with diabetes mellitus taking a sulfonylurea consumes alcohol, it can lead to disulfiram-like symptoms, such as nausea, flushing, and palpitations. Choice A, hypokalemia, is incorrect because sulfonylureas do not typically lead to low potassium levels. Choice B, hyperkalemia, is incorrect as sulfonylureas are not associated with high potassium levels. Choice C, hypocalcemia, is also incorrect because sulfonylureas are not known to cause low calcium levels.
4. A patient asks the nurse about taking calcium supplements to avoid hypocalcemia. The nurse will suggest that the patient follow which instruction?
- A. Take a calcium and vitamin D combination supplement.
- B. Take calcium along with phosphorus to improve absorption.
- C. Take calcium with antacids to reduce stomach upset.
- D. Use aspirin instead of acetaminophen when taking calcium.
Correct answer: A
Rationale: The correct answer is to take a calcium and vitamin D combination supplement. Vitamin D enhances the absorption of calcium in the body, making it an essential component for calcium utilization. Choice B is incorrect because calcium and phosphorus have an inverse relationship, where an increased level of one mineral decreases the level of the other, so taking them together may not be beneficial. Choice C is incorrect because antacids often contain magnesium, which can promote calcium loss instead of absorption. Choice D is incorrect because aspirin can alter vitamin D levels and interfere with calcium absorption, so it is not recommended when taking calcium supplements.
5. What discharge instruction is most important for a client after a kidney transplant?
- A. Weigh weekly.
- B. Report symptoms of secondary Candidiasis.
- C. Use daily reminders to take immunosuppressants.
- D. Stop cigarette smoking.
Correct answer: C
Rationale: After a kidney transplant, it is crucial for the client to adhere to the prescribed immunosuppressive therapy to prevent organ rejection. The client must take medications like corticosteroids and azathioprine (Imuran) regularly for the rest of their life. Using daily reminders is essential to ensure compliance with the medication regimen, as missing doses can increase the risk of organ rejection. Weighing weekly, reporting symptoms of secondary Candidiasis, and stopping cigarette smoking are important aspects of post-transplant care but may not be as critical as ensuring proper intake of immunosuppressants to prevent rejection.
