Nursing Elites

1. The nurse teaching a client about hepatitis and its transmission should explain that one type of hepatitis does not produce a carrier state after its acute phase. Which type is it?

• A. hepatitis A
• B. hepatitis B
• C. hepatitis C
• D. hepatitis D

Correct answer: A

Rationale: The correct answer is hepatitis A. Hepatitis A does not produce a carrier state after its acute phase. It is transmitted via contaminated water or food through the oral-fecal route and is not blood-borne. Hepatitis B, choice B, can lead to a carrier state where the person remains infectious despite being asymptomatic. Hepatitis C, choice C, can also result in a chronic carrier state. Hepatitis D, choice D, is an incomplete virus that requires hepatitis B to replicate; it does not lead to a carrier state on its own.

2. 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.

3. A client with which of the following conditions is at risk for developing a high ammonia level?

• A. renal failure
• B. psoriasis
• C. lupus
• D. cirrhosis

Correct answer: D

Rationale: Cirrhosis is the correct answer. In cirrhosis, the liver is unable to detoxify ammonia to urea, leading to an accumulation of ammonia in the blood. This can result in hepatic encephalopathy, a condition characterized by high ammonia levels affecting brain function. Renal failure (Choice A), psoriasis (Choice B), and lupus (Choice C) are not directly associated with an increased risk of high ammonia levels as seen in cirrhosis.

4. 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.

5. When observing a dressing change by a graduate nurse on a Stage III pressure ulcer to the greater trochanter by the staff nurse, a need for further teaching is indicated after the following observation by the nurse:

• A. The new graduate nurse irrigates the pressure ulcer with 50cc of NS.
• B. The new graduate irrigates the pressure ulcer with half-strength hydrogen peroxide.
• C. The new graduate packs the wound with sterile kerlix soaked in NS.
• D. The new graduate applies a Duoderm dressing over the wound after cleansing.

Correct answer: B

Rationale: The correct answer is that the new graduate irrigates the pressure ulcer with half-strength hydrogen peroxide. Pressure ulcers should not be cleaned with substances that are cytotoxic, such as hydrogen peroxide or betadine. This can cause further damage to the wound and delay the healing process. Choice A is incorrect because irrigating the pressure ulcer with normal saline is an appropriate practice. Choice C is incorrect because packing the wound with sterile kerlix soaked in normal saline is also an appropriate step. Choice D is incorrect because applying a Duoderm dressing after cleansing is a standard procedure in wound care.
