Nursing Elites

1. Why is the specific gravity for infants lower than for older children?

• A. Infants have a greater body surface area.
• B. Infants have a higher basal metabolic rate.
• C. Infants have a greater percentage of body weight that is water.
• D. Infants' kidneys are less able to concentrate urine.

Correct answer: D

Rationale: The correct answer is D because infants' kidneys are less developed compared to older children, making them less efficient at concentrating urine. This results in a lower specific gravity in infants. The other choices do not directly explain why the specific gravity is lower in infants.

2. A child is admitted to the hospital for hypercalcemia and is placed on diuretic therapy. Which diuretic would the nurse expect to administer?

• A. Furosemide (Lasix)
• B. Hydrochlorothiazide (Aquazide)
• C. Spironolactone (Aldactone)
• D. Mannitol (Osmitrol)

Correct answer: A

Rationale: Furosemide (Lasix) is a loop diuretic that acts on the ascending loop of Henle in the kidney to increase calcium excretion. In the setting of hypercalcemia, where there is an elevated level of calcium in the blood, Furosemide can help promote the elimination of excess calcium through the urine, thereby aiding in the management of hypercalcemia.

3. A child is being assessed for Kawasaki disease. Which of the following findings should be expected?

• A. Decreased heart rate
• B. Dry, scaly skin
• C. Fever unresponsive to antipyretics
• D. Nontender cervical lymphadenopathy

Correct answer: C

Rationale: In Kawasaki disease, a child typically presents with a fever that is unresponsive to antipyretics because the disease is characterized by systemic inflammation. The persistent fever is a hallmark feature of the disease and can last for more than five days despite treatment with antipyretics.

4. A caregiver is teaching a parent of a child with a new prescription for ferrous sulfate tablets. Which of the following instructions should the caregiver include in the teaching?

• A. Give the medication with milk.
• B. Take the medication on an empty stomach.
• C. Avoid giving the medication with orange juice.
• D. Brush the child's teeth after administration.

Correct answer: D

Rationale: It is important for the caregiver to instruct the parent to brush the child's teeth after administering ferrous sulfate to prevent staining of the teeth. Iron in ferrous sulfate can cause teeth discoloration, so brushing the child's teeth after taking the medication helps prevent this side effect.

5. A child receives a vaccine for MMR. Six hours after the injection, the child�s parent reports local soreness, erythema, lethargy, and a fever of 101�F to a nurse. Which action should the nurse take?

• A. Give instructions on relieving symptoms with acetaminophen
• B. Seek emergency help, because these symptoms are signs of anaphylactic reaction
• C. Tell the parent that a live vaccine will cause a mild case of measles
• D. Obtain and fill out a Vaccine Adverse Event Report form

Correct answer: A

Rationale: Low-grade fever, malaise, and muscle aches are common reactions. Acetaminophen usually alleviates these problems. MMR is a live vaccine but it is attenuated or completely avirulent and does not cause measles in healthy children, only immunocompromised children.
