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. The patient taking warfarin for prevention of deep vein thrombosis has an INR of 1.2. Which action by the nurse is most appropriate?

• A. Administer IV push protamine sulfate
• B. Continue with the current prescription.
• C. Prepare to administer Vitamin K
• D. Call healthcare provider to increase the dose

Correct answer: D

Rationale: An INR level of 1.2 is below the therapeutic range (2-3) for warfarin therapy. Therefore, the nurse should contact the healthcare provider to discuss the need for an increased dose to achieve the desired therapeutic range and prevent deep vein thrombosis effectively. Administering IV push protamine sulfate is used to reverse the effects of heparin, not warfarin. Continuing with the current prescription without addressing the subtherapeutic INR level may not effectively prevent deep vein thrombosis. Administering Vitamin K is indicated for warfarin overdose leading to excessive anticoagulation, not for a subtherapeutic INR level that is below the target range.

3. What is the priority nursing intervention when caring for a neonate born with bladder exstrophy?

• A. Measuring intake and output
• B. Inserting a Foley catheter
• C. Covering the defect with sterile plastic wrap
• D. Palpating the bladder mass to ensure urine is expelled

Correct answer: C

Rationale: The priority nursing intervention when caring for a neonate born with bladder exstrophy is to cover the defect with sterile plastic wrap. This intervention helps prevent infection and maintains a moist environment, promoting optimal healing and reducing the risk of complications.

4. A healthcare professional is performing hearing screenings for children at a community health fair. Which of the following children should the professional refer to a provider for a more extensive hearing evaluation?

• A. A toddler who is 18 months old and has unintelligible speech
• B. An infant who is 3 months old and has an exaggerated startle response
• C. A preschooler who is 4 years old and prefers playing with others rather than alone
• D. An infant who is 8 months old and is not yet making babbling sounds

Correct answer: D

Rationale: The healthcare professional should refer an infant who is not making babbling sounds by the age of 7 months to a provider for a more extensive evaluation of hearing. Babbling sounds are a developmental milestone that typically occurs by 7 months of age. Delayed or absent babbling can indicate potential hearing issues that warrant further assessment.

5. A school-age child has peripheral edema. Which of the following assessments should the nurse perform to confirm peripheral edema?

• A. Palpate the dorsum of the child's feet
• B. Weigh the child daily using the same scale
• C. Assess the child's skin turgor
• D. Observe the child for periorbital swelling

Correct answer: A

Rationale: To confirm peripheral edema in a child, the nurse should palpate the dorsum of the child's feet by pressing a fingertip against a bony prominence for 5 seconds. This assessment helps detect the presence of pitting edema, which is characterized by an indentation that remains after the pressure is released.
