Nursing Elites

1. The nurse is caring for an infant with cryptorchidism. The nurse anticipates that the most likely diagnostic study to be prescribed would be the one that assesses which item?

• A. Babinski reflex
• B. DNA synthesis
• C. Urinary function
• D. Chromosomal analysis

Correct answer: C

Rationale: Cryptorchidism, also known as undescended testes, may be caused by hormonal deficiency, intrinsic testicular abnormality, or a structural problem. Diagnostic studies for cryptorchidism typically involve assessing urinary function because the kidneys and testes originate from the same embryonic tissue. The Babinski reflex is a test for neurological function and is not relevant to evaluating cryptorchidism. DNA synthesis and chromosomal analysis are not commonly used diagnostic tests for cryptorchidism, as they are unrelated to the disorder's etiology or presentation.

2. A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

• A. Intercostal retractions
• B. Kussmaul respirations
• C. Low oxygen saturation (SpO2)
• D. Decreased venous O2 pressure

Correct answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.

3. The nurse notes that a patient has incisional pain, a poor cough effort, and scattered rhonchi after a thoracotomy. Which action should the nurse take first?

• A. Assist the patient to sit upright in a chair.
• B. Splint the patient's chest during coughing.
• C. Medicate the patient with prescribed morphine.
• D. Observe the patient use the incentive spirometer.

Correct answer: C

Rationale: The correct answer is to medicate the patient with prescribed morphine. A major reason for atelectasis and poor airway clearance in patients after chest surgery is incisional pain, which can worsen with deep breathing and coughing. The priority is to address the incisional pain to facilitate effective coughing and deep breathing, which are essential for clearing the airways and preventing complications. Assisting the patient to sit upright, splinting the patient's chest during coughing, and observing the patient using the incentive spirometer are all appropriate interventions to improve airway clearance, but they should be implemented after addressing the incisional pain with medication.

4. Administration of hepatitis B vaccine to a healthy 18-year-old patient has been effective when a specimen of the patient's blood reveals

• A. HBsAg.
• B. anti-HBs
• C. anti-HBc IgG
• D. anti-HBc IgM.

Correct answer: B

Rationale: The correct answer is 'anti-HBs'. The presence of surface antibody to HBV (anti-HBs) indicates a successful response to the hepatitis B vaccine. Anti-HBs is a marker of immunity and protection against hepatitis B infection. Choices A, C, and D are incorrect because: A) HBsAg indicates current infection with hepatitis B virus, C) anti-HBc IgG suggests past infection or immunity, and D) anti-HBc IgM is a marker of acute hepatitis B infection.

5. The mother of a child who had a cleft palate repair 4 days ago is receiving home care instructions. Which statement by the mother indicates the need for further instruction?

• A. ''I will use a short nipple on the bottle.''
• B. ''I should avoid using straws for drinking.''
• C. ''I can give my child the pacifier in 2 weeks.''
• D. ''I may give my baby food mixed with water.''

Correct answer: B

Rationale: The correct answer is ''I should avoid using straws for drinking.'' After a cleft palate repair, the child should avoid straws, pacifiers, spoons, and fingers near the mouth for 7 to 10 days to prevent injury to the surgical site. Allowing the child to use a straw can create negative pressure in the mouth, potentially disrupting the healing process. The other options are appropriate postoperative instructions for a child who had a cleft palate repair and do not pose a risk to the surgical site.
