Nursing Elites

1. How many temporary teeth should the nurse expect to find in a 5-year-old client's mouth?

• A. up to 10
• B. up to 15
• C. up to 20
• D. up to 32

Correct answer: C

Rationale: A 5-year-old child can have up to 20 temporary (deciduous or baby) teeth. The first tooth usually erupts by age 6 months, and the last by age 30 months. All temporary teeth are usually shed between 6 and 13 years of age. Therefore, a 5-year-old child should have up to 20 temporary teeth. The correct answer is 'up to 20.' Choices A, B, and D are incorrect because the correct number of temporary teeth in a 5-year-old child's mouth is up to 20, not 10, 15, or 32.

2. A nurse working the 7 a.m. to 3 p.m. shift is reviewing the records of the assigned clients. Which client should the nurse assess first?

• A. A client scheduled for hemodialysis at 10 a.m.
• B. A client scheduled for contrast computed tomography (CT) at noon.
• C. A client scheduled for a nuclear scanning procedure at 10 a.m.
• D. A client scheduled for hydrotherapy for the treatment of a burn injury at 10:30 a.m.

Correct answer: A

Rationale: The correct answer is the client scheduled for hemodialysis at 10 a.m. This client needs immediate assessment before the procedure, which may take up to 5 hours. The nurse should ensure the client is physically and emotionally prepared, check for fluid overload by assessing weight and lung sounds, review vital signs, and laboratory test results. The other clients described in the options have needs that are not as urgent. The client scheduled for a nuclear scanning procedure at 10 a.m. may require information reinforcement and increased fluid intake before the procedure. The client scheduled for hydrotherapy for the treatment of a burn injury at 10:30 a.m. may need pain medication administered 30 minutes prior to the therapy. The client scheduled for a contrast CT at noon may need procedure information reinforcement and a special contrast preparation just before the procedure.

3. The nurse is teaching a client about sleep and gives background information on normal sleep patterns. Which of the following substances promotes sleep?

• A. serotonin
• B. cortisol
• C. alcohol
• D. narcotics

Correct answer: A

Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.

4. 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.

5. While observing a client using crutches for a leg injury, which action would indicate a need for more education by the LPN?

• A. The client places the top padding 1-2 inches below the axilla with a firm grip on the handles.
• B. The client rests the axilla on the top padding and loosely grips the handles with hands.
• C. The client has a slight bend in the elbow when using the handles.
• D. When going down the stairs, the client leads with the injured leg.

Correct answer: B

Rationale: The correct answer is B. Resting the axilla on the top padding can cause nerve damage; instead, the client should place the top padding 1-2 inches below the axilla with a firm grip on the handles for proper support and stability while using crutches. Having a slight bend in the elbow when using the handles (choice C) is a correct technique to ensure proper weight distribution. Leading with the uninjured leg when going down the stairs (choice D) is the correct way to maintain balance and prevent further injury to the injured leg. Therefore, choice B indicates a need for more education to prevent potential nerve damage and ensure safe crutch use.
