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 patient is prescribed Lisinopril as part of the treatment plan for heart failure. Which finding indicates the patient is experiencing the therapeutic effect of this drug?

• A. Weight gain of 5 pounds in 1 week
• B. Potassium level of 3.5mEq/L
• C. Crackles in the lungs are no longer heard
• D. Jugular vein distention

Correct answer: C

Rationale: The correct answer is C. Lisinopril, an ACE inhibitor, promotes venous dilation, which helps reduce pulmonary congestion and peripheral edema. The absence of previously heard crackles in the lungs indicates effectiveness in reducing pulmonary congestion. Edema and jugular vein distention are signs of heart failure and would not indicate the therapeutic effect of Lisinopril. A potassium level of 3.5mEq/L is within the normal range and not directly related to the therapeutic effect of Lisinopril.

3. A school nurse is assessing a school-age child’s blood pressure while he is seated in a chair. The child starts to experience a tonic-clonic seizure. Which of the following actions should the nurse take first?

• A. Clear the immediate area around the child of hazardous objects
• B. loosen the child’s restrictive clothing
• C. assist the child to a side-lying position on the floor
• D. apply an oxygen mask to the child

Correct answer: C

Rationale: The greatest risk to this child is aspiration, occlusion of the airway, and bodily injury from falling out of the chair. The nurse should ease the child down to the floor in a side-lying position immediately.

4. A school-age child is 2 hours postoperative following a tonsillectomy. Which of the following actions should the nurse include in the plan of care?

• A. Place a heating pad at the surgical site.
• B. Encourage the child to cough every 2 hours.
• C. Administer analgesics to the child on a regular schedule.
• D. Apply an ice collar to the child's neck.

Correct answer: D

Rationale: After a tonsillectomy, applying an ice collar to the child's neck helps decrease pain and swelling. Heat should be avoided as it can increase bleeding. Encouraging coughing may increase the risk of bleeding. Administering analgesics on a regular schedule is essential for pain management, but the immediate postoperative period may require additional interventions like ice collar application.

5. Parents are speaking with the urologist about their son's undescended testicle. Which statement by the child's father causes the nurse to determine he understands the information presented?

• A. An undescended testicle can reduce fertility.
• B. The testicle usually descends spontaneously during the first month of life.
• C. Surgical correction reduces the risk for testicular tumors.
• D. The optimal time to surgically correct the condition is at diagnosis.

Correct answer: A

Rationale: The correct answer is A because an undescended testicle can reduce fertility. Even after surgical correction (orchiopexy), fertility rates may be reduced, especially when one testis remains undescended. The statement in choice B is incorrect as the testicle should have descended into the scrotum by the time the infant is 4-6 months old. While choice C is true that surgical correction can reduce the risk of testicular tumors, the question focuses on the father's understanding of the information presented, which is better reflected in choice A. Choice D is incorrect because the optimal time for surgical correction of an undescended testicle is typically around 6-18 months of age, not necessarily at the time of diagnosis.
