Nursing Elites

1. In caring for a client receiving the aminoglycoside antibiotic gentamicin, what diagnostic test should the nurse prioritize monitoring?

• A. Urinalysis
• B. Serum creatinine
• C. Serum osmolarity
• D. Liver enzymes

Correct answer: B

Rationale: The correct answer is B: Serum creatinine. Aminoglycosides, such as gentamicin, are known to cause nephrotoxicity, which can lead to kidney damage. Monitoring serum creatinine levels is crucial in assessing renal function and detecting any potential kidney problems early. Choices A, C, and D are incorrect because urinalysis primarily assesses urine composition, serum osmolarity measures the concentration of solutes in the blood, and liver enzymes are not directly impacted by aminoglycoside antibiotics like gentamicin.

2. The nurse is assisting the mother of a child with phenylketonuria (PKU) to select foods that are in keeping with the child's dietary restrictions. Which foods are contraindicated for this child?

• A. Wheat products
• B. Foods sweetened with aspartame
• C. High-fat foods
• D. High-calorie foods

Correct answer: B

Rationale: The correct answer is B: Foods sweetened with aspartame. Aspartame should not be consumed by a child with PKU because it is converted to phenylalanine in the body, which can be harmful to individuals with PKU. Choice A (Wheat products) is not specifically contraindicated for PKU. Choice C (High-fat foods) and Choice D (High-calorie foods) are not typically restricted in PKU diets unless they contain high levels of phenylalanine.

3. A client with a postoperative wound that eviscerated yesterday has an elevated temperature. What is the most important intervention for the nurse to implement?

• A. Initiate contact isolation.
• B. Obtain a wound swab for culture and sensitivity.
• C. Assess temperature every 4 hours.
• D. Use alcohol-based solutions for hand hygiene.

Correct answer: B

Rationale: Obtaining a wound swab for culture and sensitivity is the most important intervention in this situation. It helps identify the presence of infection in the postoperative wound that could be causing the elevated temperature. By obtaining a wound swab, healthcare providers can determine the appropriate treatment needed to address any infection. Initiating contact isolation (Choice A) may be necessary in certain situations but is not the priority in this case. Assessing temperature (Choice C) is important but does not directly address the underlying cause of the elevated temperature. Using alcohol-based solutions for hand hygiene (Choice D) is a standard practice for infection control but is not the most crucial intervention in this scenario.

4. A client with chronic heart failure is receiving furosemide (Lasix). Which assessment finding requires immediate intervention?

• A. Heart rate of 60 beats per minute
• B. Blood pressure of 110/70 mmHg
• C. Crackles in the lungs
• D. Peripheral edema

Correct answer: C

Rationale: In a client with chronic heart failure receiving furosemide, crackles in the lungs indicate pulmonary congestion, requiring immediate intervention. This finding suggests fluid accumulation in the lungs, impairing oxygen exchange and potentially leading to respiratory distress. Monitoring and managing pulmonary congestion promptly are crucial to prevent worsening heart failure and respiratory compromise. The other options, while important to assess in a client with heart failure, do not indicate an immediate need for intervention like crackles in the lungs do. A heart rate of 60 beats per minute may be within the normal range for some individuals, a blood pressure of 110/70 mmHg is relatively stable, and peripheral edema is a common manifestation of heart failure that should be monitored but does not require immediate intervention compared to pulmonary congestion.

5. After placing a stethoscope as seen in the picture, the nurse auscultates S1 and S2 heart sounds. To determine if an S3 heart sound is present, what action should the nurse take first?

• A. Slide the stethoscope across the sternum.
• B. Move the stethoscope to the mitral site.
• C. Listen with the bell at the same location.
• D. Observe the cardiac telemetry monitor.

Correct answer: C

Rationale: The nurse uses the bell of the stethoscope to hear low-pitched sounds such as S3 and S4. To determine if an S3 heart sound is present, the nurse should listen at the same location using the bell first. This allows for the accurate identification of low-pitched sounds. Moving the stethoscope across the sternum (Choice A) or to the mitral site (Choice B) would not be the initial actions to assess for an S3 heart sound. Observing the cardiac telemetry monitor (Choice D) is not relevant for assessing S3 heart sounds, as it does not provide direct auscultation of heart sounds.
