Nursing Elites

1. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client’s respiratory acidosis?

• A. Low oxygen levels are present in the blood.
• B. High levels of carbon dioxide have accumulated in the blood.
• C. Increased bicarbonate levels are causing alkalosis.
• D. Respiratory rate is increased, causing hyperventilation.

Correct answer: B

Rationale: High levels of carbon dioxide in the blood lead to respiratory acidosis due to inadequate ventilation. The correct answer is B. In respiratory acidosis, the accumulation of carbon dioxide in the blood occurs due to inadequate exhalation, leading to acidosis. Choice A is incorrect as low oxygen levels are related to hypoxemia, not respiratory acidosis. Choice C is incorrect as increased bicarbonate levels would lead to alkalosis, not acidosis. Choice D is incorrect as an increased respiratory rate causing hyperventilation would actually help decrease carbon dioxide levels, not lead to respiratory acidosis.

2. Which type of lipoprotein is associated with decreasing the risk of atherosclerosis?

• A. High-density lipoprotein (HDL)
• B. Low-density lipoprotein (LDL)
• C. Very low-density lipoprotein (VLDL)
• D. Intermediate-density lipoprotein (IDL)

Correct answer: A

Rationale: The correct answer is High-density lipoprotein (HDL). HDL is known as 'good' cholesterol because it helps remove cholesterol from the arteries, reducing the risk of atherosclerosis. LDL (choice B) is considered 'bad' cholesterol as it can deposit cholesterol in the arteries, increasing the risk of atherosclerosis. VLDL (choice C) and IDL (choice D) are also associated with increased risk of atherosclerosis rather than decreasing it.

3. An infant has been diagnosed with cradle cap. What is the correct intervention to treat the scalp?

• A. Alcohol
• B. Mineral oil
• C. Calamine
• D. A&D ointment

Correct answer: B

Rationale: Cradle cap is a common condition in infants characterized by crusty patches on the scalp. The correct intervention to treat cradle cap is to apply mineral oil. Mineral oil helps soften the crusty patches, making it easier to remove them gently. Alcohol (Choice A) can be too harsh for an infant's sensitive skin and may cause irritation. Calamine (Choice C) is used to relieve itching associated with conditions like chickenpox or insect bites, not for treating cradle cap. A&D ointment (Choice D) is typically used for diaper rash and minor skin irritations, not for cradle cap.

4. Which other congenital defects are common in children with Down syndrome?

• A. Hypospadias
• B. Pyloric stenosis
• C. Heart defects
• D. Hip dysplasia

Correct answer: C

Rationale: The correct answer is C: Heart defects. Many children with Down syndrome are born with congenital heart defects. These heart abnormalities are more prevalent in individuals with Down syndrome than in the general population. Choices A, B, and D are incorrect because while they may be congenital defects in children, they are not commonly associated with Down syndrome. Hypospadias is a urogenital condition, pyloric stenosis affects the stomach, and hip dysplasia involves the hip joint, but these are not typically seen as frequently as heart defects in children with Down syndrome.

5. An adolescent female asks the nurse about taking retinoic acid (Accutane). What guidance should be provided by the nurse?

• A. The medication should be used for 10 weeks only.
• B. The medication requires that sexually active females use contraception.
• C. The medication lowers hemoglobin levels very quickly.
• D. The medication has few side effects.

Correct answer: B

Rationale: The correct guidance the nurse should provide is that sexually active females must use contraception while taking Accutane and for 1 month after the 20 weeks it is prescribed. Choice A is incorrect because Accutane is typically taken for a longer duration than 10 weeks. Choice C is incorrect because Accutane does not lower hemoglobin levels quickly. Choice D is incorrect as Accutane is known for having many side effects, including the risk of birth defects.
