1. Which of the following isoenzymes is elevated in a client who has had a myocardial infarction?

• A. CPK-BB
• B. CPK-MM
• C. CPK-MB
• D. CPK-MI

Correct answer: C

Rationale: CPK-MB is the correct answer as it is elevated in clients who have had a myocardial infarction. CPK-BB is elevated in clients with brain damage, and CPK-MM is elevated in clients with skeletal muscle damage. CPK-MI, mentioned in the rationale, does not exist, making it an incorrect choice.

2. What is the 24-hour day-night cycle known as?

• A. circadian rhythm
• B. infradian rhythm
• C. ultradian rhythm
• D. non-REM rhythm

Correct answer: A

Rationale: The correct answer is circadian rhythm. Circadian rhythm refers to the rhythmic repetition of patterns that occur approximately every 24 hours, regulating various biological processes related to the day-night cycle. Infradian rhythm, which is longer than 24 hours, and ultradian rhythm, which is shorter than 24 hours, are not the correct terms for the 24-hour cycle. Non-REM rhythm does not specifically relate to the 24-hour day-night cycle, making it an incorrect choice.

3. Which of the following nursing diagnoses is most appropriate for a client with a new colostomy?

• A. Excess Fluid Volume
• B. Risk for Aspiration
• C. Disturbed Body Image
• D. Urinary Retention

Correct answer: C

Rationale: Disturbed Body Image is the most appropriate nursing diagnosis for a client with a new colostomy. A new colostomy can significantly impact a person's body image and self-esteem due to the physical changes it brings. This can lead to emotional distress, adjustment issues, and concerns about body image. Excess Fluid Volume, Risk for Aspiration, and Urinary Retention are not directly related to the psychosocial impact of a new colostomy and are therefore not as relevant in this context. While Excess Fluid Volume, Risk for Aspiration, and Urinary Retention are important nursing diagnoses, they are not the priority when considering the psychological and emotional effects of a new colostomy.

4. Which of these clients should the LPN/LVN see first?

• A. a client with a newly placed NG tube who is complaining of pain around the face and a plugged nose
• B. a post-op prostatectomy client who complains of bladder spasms and blood in his foley bag
• C. a client in an arm cast who is 2 days post-op and reports feelings of numbness and tingling in her affected arm
• D. a client newly diagnosed with Hepatitis A who reports stomach pain and itchy skin

Correct answer: C

Rationale: Numbness and tingling hours or days after a cast is applied may indicate compartment syndrome and should be reported to a medical provider right away. This is a potential emergency situation that requires immediate attention to prevent complications. The other options present expected or typical symptoms related to their diagnosis, which do not require immediate intervention. Complaints related to a newly placed NG tube such as pain around the face and a plugged nose may require assessment and intervention but are not as urgent as potential compartment syndrome. Bladder spasms and blood in the foley bag post-prostatectomy are common postoperative issues that can be addressed after the client in the arm cast with potential compartment syndrome is seen. Stomach pain and itchy skin in a client with Hepatitis A are common symptoms of the condition and do not indicate an emergency situation.

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.
