Nursing Elites

1. An adult female client has undergone a routine health screening in the clinic. Which of the following values indicates to the nurse who receives the report of the client’s laboratory work that the client’s hematocrit is normal?

• A. 10%
• B. 22%
• C. 30%
• D. 43%

Correct answer: D

Rationale: The normal hematocrit for an adult female client ranges from 35% to 47%. A hematocrit value of 43% falls within this normal range, indicating normal levels of red blood cells. Choices A, B, and C are low hematocrit values and are considered below the normal range for adult females, signifying potential anemia or other health issues.

2. The nurse is caring for a patient who is taking trimethoprim-sulfamethoxazole (TMP-SMX). The nurse learns that the patient takes an angiotensin-converting enzyme (ACE) inhibitor. To monitor for drug interactions, the nurse will request an order for which laboratory test(s)?

• A. A complete blood count
• B. BUN and creatinine
• C. Electrolytes
• D. Glucose

Correct answer: C

Rationale: The correct answer is 'C. Electrolytes.' When trimethoprim-sulfamethoxazole (TMP-SMX) is taken with an ACE inhibitor, there is an increased risk of hyperkalemia due to the combined effects on potassium levels. Monitoring electrolytes, specifically potassium, is essential to detect and manage this potential drug interaction. Choices A, B, and D are incorrect because while they are important tests in general patient care, they are not specifically indicated to monitor for the drug interaction between TMP-SMX and ACE inhibitors.

3. The nurse is preparing to administer clarithromycin to a patient. When performing a medication history, the nurse learns that the patient takes warfarin to treat atrial fibrillation. The nurse will perform which action?

• A. Ask the provider if azithromycin may be used instead of clarithromycin.
• B. Obtain an order for continuous cardiovascular monitoring.
• C. Request an order for periodic serum warfarin levels.
• D. Withhold the clarithromycin and notify the provider.

Correct answer: C

Rationale: When a patient taking warfarin also needs to receive clarithromycin, it is essential to monitor periodic serum warfarin levels. Macrolides, including clarithromycin, can increase serum levels of drugs like warfarin. Monitoring serum drug levels helps ensure that the patient's warfarin dose can be adjusted, if necessary, to maintain therapeutic levels. Asking about using azithromycin instead is not the most appropriate action in this situation, as all macrolides can interact with warfarin. Continuous cardiovascular monitoring is not indicated solely based on the use of clarithromycin. Withholding the clarithromycin without proper assessment could delay necessary treatment and is not the best initial action.

4. Which food is most important to encourage a client with osteomalacia to include in a daily diet?

• A. Fortified milk and cereals
• B. Citrus fruits and juices
• C. Green leafy vegetables
• D. Red meats and eggs

Correct answer: A

Rationale: The correct answer is A: Fortified milk and cereals. Osteomalacia is a condition caused by a deficiency in vitamin D. Fortified milk and cereals are rich sources of vitamin D, which is essential for managing osteomalacia. Citrus fruits and juices (choice B) are high in vitamin C, but vitamin D is the primary concern for osteomalacia. Green leafy vegetables (choice C) are good sources of various nutrients but not the main focus for managing osteomalacia. Red meats and eggs (choice D) are good sources of protein and other nutrients but are not as critical as fortified milk and cereals for addressing vitamin D deficiency in osteomalacia.

5. The healthcare professional is preparing to give a dose of trimethoprim-sulfamethoxazole (TMP-SMX) and learns that the patient takes warfarin (Coumadin). The healthcare professional will request an order for

• A. a decreased dose of TMP-SMX.
• B. a different antibiotic.
• C. an increased dose of warfarin.
• D. coagulation studies.

Correct answer: D

Rationale: Sulfonamides, like trimethoprim-sulfamethoxazole (TMP-SMX), can potentiate the anticoagulant effects of warfarin (Coumadin). To monitor the patient's response and prevent adverse effects, the healthcare professional should request coagulation studies, such as International Normalized Ratio (INR) levels. Choosing a decreased dose of TMP-SMX would not address the potential drug interaction between TMP-SMX and warfarin. Opting for a different antibiotic is not necessary if the interaction can be managed by monitoring. Increasing the dose of warfarin without monitoring could lead to excessive anticoagulation and adverse events, so it's not the appropriate action in this scenario.
