Nursing Elites

1. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?

• A. Metabolic acidosis
• B. Respiratory alkalosis
• C. Metabolic and respiratory acidosis
• D. Metabolic and respiratory alkalosis

Correct answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.

2. What pathologic process is believed to be responsible for the development of postinfectious glomerulonephritis?

• A. Infarction of renal vessels
• B. Immune complex formation and glomerular deposition
• C. Bacterial endotoxin deposition on and destruction of glomeruli
• D. Embolization of glomeruli by bacteria and fibrin from endocardial vegetation

Correct answer: B

Rationale: Postinfectious glomerulonephritis is typically caused by immune complex deposition in the glomeruli following a streptococcal infection. This immune response leads to inflammation and impaired kidney function.

3. What is typically the first sign of puberty in females?

• A. Breast development
• B. Menarche
• C. Pubic hair growth
• D. Axillary hair growth

Correct answer: A

Rationale: The correct answer is A: Breast development (thelarche) is usually the first sign of puberty in females, typically beginning between ages 8 and 13. This marks the start of puberty, followed by pubic hair growth, a growth spurt, and eventually menarche (the onset of menstruation). Pubic hair growth and axillary hair growth usually follow breast development in the sequence of pubertal changes. Therefore, the first noticeable change indicating the onset of puberty in females is the development of breast buds.

4. What is an essential nursing care intervention for a neonate with a suspected tracheoesophageal fistula?

• A. Feed glucose water only.
• B. Elevate the patient's head for feedings.
• C. Raise the patient's head and give nothing by mouth.
• D. Avoid suctioning unless the infant is cyanotic.

Correct answer: C

Rationale: Raising the patient’s head and giving nothing by mouth is crucial in managing tracheoesophageal fistula. This intervention helps prevent aspiration and further complications until surgical correction can be performed. Feeding the neonate or suctioning could exacerbate the condition by risking aspiration. Elevating the head for feedings does not address the primary concern of preventing oral intake, making it less appropriate than the correct answer.

5. The nurse is caring for a child with a urinary tract infection who is on intravenous gentamicin (Garamycin). What interventions should the nurse plan for this child with regard to this medication? (Select all that apply.)

• A. Encourage fluids.
• B. Monitor urinary output.
• C. Monitor sodium serum levels.
• D. All above

Correct answer: D

Rationale: Gentamicin is an aminoglycoside antibiotic that requires monitoring of serum peak and trough levels to avoid toxicity, particularly nephrotoxicity and ototoxicity. Encouraging fluids and monitoring urinary output are also crucial to minimize the risk of kidney damage.
