Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. ARDS is characterized by severe hypoxemia, and oxygen therapy is essential to improve oxygenation. Administering corticosteroids (B) is not recommended as they do not improve outcomes in ARDS. Monitoring serum glucose (C) is unrelated to the treatment of ARDS. Administering pain relief (D) is important for patient comfort but does not address the underlying hypoxemia in ARDS. Oxygen therapy is the primary treatment to support respiratory function and improve oxygen delivery in ARDS.

Correct Answer: A

Rationale: The correct answer is A: Administer epinephrine. This is the first step in the care of a client with a severe allergic reaction because epinephrine is the primary medication used to reverse the life-threatening symptoms of anaphylaxis. Epinephrine acts quickly to constrict blood vessels, relax smooth muscles in the lungs to improve breathing, and increase heart rate. Administering epinephrine promptly can prevent progression to severe outcomes like respiratory failure or shock. Corticosteroids (B and C) are used as adjunct therapy and do not provide immediate relief. Applying a cold compress (D) does not address the systemic effects of anaphylaxis and can delay potentially life-saving treatment.

Correct Answer: B

Rationale: The correct answer is B because it demonstrates active listening and seeks clarification on the issue at hand. By asking the woman to explain what she means by "fits," the nurse can gain a better understanding of the child's behavior and provide appropriate support and guidance. This response shows empathy and a willingness to address the woman's concerns effectively. Choice A is incorrect because it does not address the woman's specific concerns or invite further discussion. Choice C is incorrect because it simply acknowledges the woman's feelings without delving deeper into the issue. Choice D is incorrect as it dismisses the woman's feelings and generalizes the behavior as typical for all 2-year-olds without addressing her individual situation.

Correct Answer: A

Rationale: The correct answer is A: Blood urea nitrogen (BUN). In CKD, the kidneys are unable to effectively filter waste products, leading to an increase in BUN levels. Elevated BUN indicates impaired kidney function. Calcium, potassium, and sodium levels may also be affected in CKD, but they are more likely to be imbalanced rather than consistently elevated. Calcium levels may be low due to impaired vitamin D activation, potassium levels may be high due to decreased excretion, and sodium levels can fluctuate based on fluid status. Therefore, while these lab values may be abnormal in CKD, BUN is the most consistently elevated marker of kidney dysfunction.

Correct Answer: A

Rationale: Step 1: Lisinopril is an ACE inhibitor commonly prescribed post-myocardial infarction to reduce strain on the heart and prevent further damage. Step 2: ACE inhibitors like Lisinopril help lower blood pressure and improve heart function. Step 3: By reducing the workload on the heart, Lisinopril can help prevent complications post-MI. Step 4: Acetaminophen (B) is a pain reliever and does not address the cardiovascular issues post-MI. Step 5: Furosemide (C) and Hydrochlorothiazide (D) are diuretics typically used for managing fluid retention, not the primary focus after an MI. Summary: Lisinopril is the correct choice as it helps improve heart function and prevent complications post-MI, unlike the other options which do not directly address the cardiovascular issues associated with MI.
