Nursing Elites

1. 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.

2. 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.

3. Which of the following enzymes is indicative of pancreatitis?

• A. alkaline phosphatase
• B. acid phosphatase
• C. creatine phosphokinase
• D. amylase

Correct answer: D

Rationale: Amylase is elevated in conditions of pancreatic inflammation, such as pancreatitis. Pancreatitis is characterized by the inflammation of the pancreas, leading to the leakage of amylase into the bloodstream. Elevated levels of amylase are a key diagnostic marker for pancreatitis. Alkaline phosphatase is associated with liver and bone conditions, not pancreatitis. Acid phosphatase is more related to prostate health and is not specific to pancreatitis. Creatine phosphokinase is found in tissues like muscle and brain, and elevated levels are seen in conditions like muscle injury or heart attack, not pancreatitis.

4. 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.

5. Why is padding on a restraint helpful?

• A. To distribute pressure so that bony prominences do not receive pressure when a client pulls against the restraints.
• B. To help the client feel more secure.
• C. To keep infection and wounds at bay.
• D. To keep restraints in place.

Correct answer: A

Rationale: Padding on a restraint helps distribute pressure to prevent bony prominences from bearing excessive pressure when a client pulls against the restraints. This is crucial to avoid tissue damage caused by ischemia. The correct answer focuses on the physiological benefit of padding in reducing pressure on vulnerable areas to prevent harm. Choice B is incorrect as the primary purpose of padding is not emotional comfort but preventing physical harm. Choice C is incorrect as while padding can indirectly help prevent infection and wounds by reducing pressure, its primary function is pressure distribution. Choice D is incorrect as the main purpose of padding is not to keep the restraints in place but to protect the client's skin and tissues from pressure-related injuries.
