1. 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.

2. The nurse in the emergency room is admitting a client who has sustained a gunshot wound and will require immediate surgery. The client is unconscious and by themselves. Which of the following actions is most appropriate?

• A. Call the charge nurse and request that the facility's legal counsel provide a waiver for informed consent.
• B. Attempt to stabilize the client in the emergency room until they are conscious enough to provide informed consent.
• C. Try to locate the client's family to obtain informed consent before transporting the client to the operating room.
• D. Proceed with transporting the client to the operating room without obtaining informed consent.

Correct answer: D

Rationale: In emergency situations where a client is unconscious and requires immediate surgery to save their life, the priority is to proceed with necessary interventions without delay to ensure the best possible outcome. Obtaining informed consent is essential in healthcare, but in situations where a delay in treatment can be life-threatening, healthcare providers are ethically and legally permitted to proceed with treatment without consent. Attempting to stabilize the client until conscious enough to provide consent or trying to locate family members for consent would cause a dangerous delay in critical care. Therefore, the most appropriate action in this scenario is to transport the unconscious client to the operating room for immediate surgery.

3. Pulling is easier than pushing. So pulling a client rather than pushing them has which of the following advantages?

• A. reduces workload
• B. decreases opposition from gravity
• C. maintains stability
• D. prevents muscle strain

Correct answer: A

Rationale: When pulling a client, you work with the gravitational force instead of opposing it, which reduces the workload on your muscles. Choosing to pull a client minimizes the effort required compared to pushing. Choice B is incorrect because the force of gravity remains constant regardless of pushing or pulling. Choice C is irrelevant as stability is not directly related to the advantage of pulling over pushing. Choice D is inaccurate because pulling can still strain muscles if not executed correctly, but it generally reduces the overall workload in comparison to pushing.

4. A new mother asks the nurse, 'I was told that my infant received my antibodies during pregnancy. Does that mean that my infant is protected against infections?' Which statement should the nurse make in response to the mother?

• A. The immune system of an infant is immature, and the infant is at risk for infection.
• B. The transfer of your antibodies protects your infant until the infant is 12 months old.
• C. Yes, your infant is protected from all infections.
• D. If you breastfeed, your infant is protected from infection.

Correct answer: A

Rationale: The transplacental transfer of maternal antibodies supplements the infant's weak response to infection until approximately 3 to 4 months of age. While the infant starts producing immunoglobulin (Ig) soon after birth, it only reaches about 60% of the adult IgG level, 75% of the adult IgM level, and 20% of the adult IgA level by 1 year of age. Breast milk provides additional IgA protection. Although the immune system matures during infancy, full protection against infections is not achieved until early childhood, putting the infant at risk for infections. Choice B is incorrect because maternal antibody protection typically lasts around 3 to 4 months, not until the infant is 12 months old. Choice C is incorrect as infants are not shielded from all infections due to their immature immune system. Choice D is incorrect because while breastfeeding offers extra protection, it does not guarantee complete immunity against infections.

5. 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.
