Nursing Elites

1. The nurse is caring for a client who is receiving total parenteral nutrition (TPN) via a central venous catheter. Which assessment finding indicates a complication related to the TPN?

• A. Blood glucose level of 180 mg/dl
• B. Serum potassium level of 4.0 mEq/L
• C. Weight gain of 2 pounds in 24 hours
• D. White blood cell count of 7000/mm3

Correct answer: C

Rationale: A weight gain of 2 pounds in 24 hours is concerning as it indicates fluid retention, a potential complication of TPN leading to fluid overload. Elevated blood glucose levels (Choice A) are expected in TPN, serum potassium levels (Choice B) are within the normal range, and a white blood cell count (Choice D) of 7000/mm3 is also normal. Therefore, the correct answer is C, as it suggests a complication related to TPN.

2. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

3. When caring for a laboring client whose contractions are occurring every 2 to 3 min, the nurse should document that the pump is infusing how many ml/hr?

• A. 42
• B. 50
• C. 60
• D. 70

Correct answer: A

Rationale: To calculate the infusion rate, we first need to determine the frequency of contractions per hour. If contractions are occurring every 2 to 3 minutes, this corresponds to 20 to 30 contractions in an hour (60 minutes). The average is 25 contractions in an hour. The pump should be infusing 1 ml for each contraction, so the infusion rate should be 25 ml/hr. Therefore, the correct answer is 42 ml/hr. Choices B, C, and D are incorrect as they do not align with the calculation based on the given data.

4. The nurse-manager of a perinatal unit is notified that one client from the medical-surgical unit needs to be transferred to make room for new admissions. Which client should the nurse recommend for transfer to the antepartal unit?

• A. A 45-year-old with chronic hepatitis B.
• B. A 35-year-old with lupus erythematosus
• C. A 19-year-old diagnosed with rubella
• D. A 25-year-old with herpes lesions of the vulva

Correct answer: B

Rationale: The correct answer is B because a client with lupus erythematosus can be safely transferred to the antepartal unit as this condition does not pose a significant risk to other patients or staff. Choices A, C, and D should not be recommended for transfer to the antepartal unit due to the potential risks they may pose to pregnant women and their unborn babies. Chronic hepatitis B, rubella, and herpes lesions of the vulva can be contagious and harmful in the perinatal setting.

5. Which assessment finding is most indicative of deep vein thrombosis (DVT) in a client's right leg?

• A. Dorsiflexes the right foot and left on command
• B. A 3 by 5 cm ecchymosis area covering the right calf
• C. Right calf is 3 cm larger in circumference than the left
• D. Bilateral lower extremity has 3+ pitting edema

Correct answer: C

Rationale: The correct answer is C because a significant increase in the circumference of the right calf compared to the left calf is a classic sign of deep vein thrombosis (DVT). Option A is incorrect as dorsiflexing the right foot and left on command does not specifically indicate DVT. Option B describes an ecchymosis area which is more indicative of a bruise rather than DVT. Option D suggests bilateral lower extremity edema, which is not specific to DVT and can be seen in various conditions such as heart failure or renal issues.
