1. Which of the following represents a normal serum potassium level?

• A. 1.5 mEq/L
• B. 3.0 mEq/L
• C. 4.0 mEq/L
• D. 6.0 mEq/L

Correct answer: C

Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).

2. A child comes to the clinic with a skin rash. The maculopapular lesions are distributed around the mouth and have honey-colored drainage. The caregiver states that the rash is getting worse and seems to spread with the child's scratching. Which of the following advisory comments should be given?

• A. The history and presentation might indicate chickenpox, a highly contagious disease.
• B. The lesions might indicate a noncontagious infection that does not require isolation.
• C. The history and presentation might indicate an infectious illness called impetigo.
• D. The lesions are not contagious unless others have open wounds or lesions themselves.

Correct answer: C

Rationale: The scenario describes classic impetigo, which typically presents with maculopapular lesions around the mouth with honey-colored drainage, worsening with scratching. It is important to advise the caregiver that the history and presentation are indicative of impetigo, an infectious skin condition caused by bacteria. Treatment usually involves antibiotic therapy. Choice A is incorrect because chickenpox typically presents with a vesicular rash following a history of high fever. Choice B is incorrect as impetigo is contagious and requires precautions to prevent the spread of infection. Choice D is incorrect as impetigo is contagious irrespective of open wounds or lesions in others.

3. What should be included in the assessment of a client with a cast?

• A. capillary refill, warm toes, no discomfort.
• B. posterior tibial pulses, warm toes.
• C. moist skin essential, pain threshold.
• D. discomfort of the metacarpals.

Correct answer: A

Rationale: When assessing a client with a cast, it is crucial to check for capillary refill to ensure adequate circulation. Warm toes indicate good circulation, while the absence of discomfort suggests the cast is not causing any pain or undue pressure on the client. Therefore, choices B, C, and D are incorrect as they do not address the essential components of assessing a client with a cast.

4. The LPN is caring for a 32-year-old female client who is 8 hours post-op after a tonsillectomy. Which of these actions would be appropriate for the nurse to take?

• A. Inform the client that ear pain may occur and is normal.
• B. Provide ice water and a straw to promote easy fluid consumption.
• C. Provide hot tea to soothe the throat.
• D. Monitor vitals every 15 minutes.

Correct answer: A

Rationale: The appropriate action for the nurse to take is to inform the client that ear pain may occur and is normal after a tonsillectomy. Referred pain in the ear is common due to related nerve pathways. It is essential to educate the client about this to alleviate concerns. Providing ice water and a straw is not recommended as they may irritate the throat and disturb the healing process. Hot beverages like tea should also be avoided for the same reason. While monitoring vitals every 15 minutes is crucial in the immediate postoperative period for early identification of any complications, it is not the most appropriate action in this scenario where addressing the client's concerns and providing education is key.

5. When evaluating the lab work of a client in hepatic coma, which of the following lab tests is most important?

• A. blood urea nitrogen
• B. serum calcium
• C. serum ammonia
• D. serum creatinine

Correct answer: C

Rationale: When a client is in hepatic coma due to liver failure, the liver cannot metabolize amino acids completely, leading to elevated ammonia levels. Increased ammonia can cause brain-tissue irritation, worsening the coma. Therefore, monitoring serum ammonia levels is crucial in assessing the severity of hepatic coma. Choices A, B, and D are less relevant in the context of hepatic coma. Blood urea nitrogen primarily assesses kidney function, serum calcium levels are not directly related to hepatic coma, and serum creatinine is more indicative of kidney function rather than liver function in this scenario.
