Nursing Elites

1. 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.

2. A client who is postmenopausal and has had two episodes of bacterial urethritis in the last 6 months asks, “I never have urinary tract infections. Why is this happening now?” How should the nurse respond?

• A. Your immune system becomes less effective as you age.
• B. Low estrogen levels can make the tissue more susceptible to infection.
• C. You should be more careful with your personal hygiene in this area.
• D. It is likely that you have an untreated sexually transmitted disease.

Correct answer: B

Rationale: Low estrogen levels in postmenopausal women decrease moisture and secretions in the perineal area, causing tissue changes that predispose them to infection, including urethritis. This is a common reason for urethritis in postmenopausal women. While immune function does decrease with aging and sexually transmitted diseases can cause urethritis, the most likely reason in this case is the low estrogen levels. Personal hygiene practices are usually not a significant factor in the development of urethritis.

3. A female patient who is allergic to penicillin will begin taking an antibiotic to treat a lower respiratory tract infection. The patient tells the nurse that she almost always develops a vaginal yeast infection when she takes antibiotics and that she will take fluconazole (Diflucan) with the antibiotic being prescribed. Which macrolide should the nurse question for this patient?

• A. Azithromycin (Zithromax)
• B. Clarithromycin (Biaxin)
• C. Erythromycin (E-Mycin)
• D. Fidaxomicin (Dificid)

Correct answer: C

Rationale: The nurse should question the prescription of erythromycin for this patient. When erythromycin is given concurrently with fluconazole, erythromycin blood concentration and the risk of sudden cardiac death increase. Therefore, it is not recommended to use erythromycin in combination with fluconazole for this patient. Azithromycin, clarithromycin, and fidaxomicin are alternative macrolide antibiotics that can be considered for this patient without the same risk of interactions when used with fluconazole.

4. A nurse is assessing a postoperative client on an hourly basis. The nurse notes that the client’s urine output for the past hour was 25 mL. Based on this finding, the nurse first:

• A. Calls the physician
• B. Increases the rate of the IV infusion
• C. Checks the client’s overall intake and output record
• D. Administers a 250-mL bolus of normal saline solution (0.9%)

Correct answer: C

Rationale: Clients are at risk of hypovolemia postoperatively, and decreased urine output can be an early sign. However, to accurately interpret this finding, the nurse must assess the overall fluid balance by checking the client’s intake and output records. Increasing the IV infusion rate or administering a bolus of normal saline solution without a physician's order would not be appropriate as these interventions require a prescription. The physician should be notified once the nurse has collected all necessary assessment data, including fluid status and vital signs.

5. The nurse is planning care for an older adult client who experienced a cerebrovascular accident several weeks ago. The client has expressive aphasia and often becomes frustrated with the nursing staff. Which intervention should the nurse implement?

• A. Teach the client the use of basic sign language
• B. Speak slowly to the client
• C. Encourage the client's use of picture charts
• D. Ask the client simple questions

Correct answer: C

Rationale: Encouraging the client's use of picture charts is the most appropriate intervention for a client with expressive aphasia. Picture charts provide visual cues that can aid in communication and reduce frustration for the client. This intervention can help the client express their needs and thoughts effectively. Teaching sign language (Choice A) may be challenging and not as practical in this situation as it may not address the specific communication barriers caused by expressive aphasia. Speaking slowly (Choice B) may not fully address the communication difficulties associated with expressive aphasia. Asking simple questions (Choice D) may not be effective as the client may have difficulty understanding and responding due to the nature of expressive aphasia.
