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. An intravenous line is needed in a school-age child. What medication is an appropriate analgesic for use with this patient?

• A. TAC (tetracaine, epinephrine [Adrenalin], cocaine) 15 minutes before the procedure.
• B. A transdermal fentanyl (Duragesic) patch at the site of venipuncture.
• C. EMLA (eutectic mixture of local anesthetics) immediately before the procedure.
• D. LMX (4% liposomal lidocaine cream) 30 minutes before the procedure.

Correct answer: D

Rationale: LMX is an effective analgesic agent when applied to the skin 30 minutes before a procedure. It eliminates or reduces the pain from most procedures involving skin puncture. TAC provides skin anesthesia about 15 minutes after application to nonintact skin, making it more suitable for wound suturing. Transdermal fentanyl patches are designed for continuous pain control, not rapid pain control needed for a procedure like venipuncture. EMLA, for maximum effectiveness, must be applied approximately 60 minutes before the procedure, making it less suitable for immediate pain relief required for intravenous line placement.

3. The nurse is performing an assessment on a 10-week-old infant. The nurse understands that the developmental characteristic of hearing at this age is which?

• A. The infant responds to his own name.
• B. The infant localizes sounds by turning his head directly to the sound.
• C. The infant turns his head to the side when sound is made at the level of the ear.
• D. The infant locates sound by turning his head to the side and then looking up or down.

Correct answer: C

Rationale: By 10 weeks, infants typically turn their heads to the side to locate the source of a sound made at ear level.

4. A 14-month-old child is admitted to the hospital with laryngotracheobronchitis (LTB). Which assessment findings should the nurse expect?

• A. Cyanosis and dyspnea
• B. Productive cough and high fever
• C. Barking cough and inspiratory stridor
• D. Pale laryngeal and dyspnea

Correct answer: C

Rationale: The correct answer is C: 'Barking cough and inspiratory stridor.' Classic signs of laryngotracheobronchitis (LTB) include a barking cough, often described as a seal-like cough, and inspiratory stridor, which is a high-pitched sound heard during inspiration. These symptoms occur due to inflammation and narrowing of the upper airway. Choices A, B, and D are incorrect as they do not align with the typical assessment findings of LTB. Cyanosis and dyspnea (Choice A) may occur in severe cases but are not specific to LTB. Productive cough and high fever (Choice B) are more indicative of lower respiratory tract infections. Pale laryngeal and dyspnea (Choice D) are not characteristic findings of LTB.

5. A nurse is evaluating the effectiveness of teaching regarding care of a child with minimal change nephrotic syndrome (MCNS) that is in remission after the administration of prednisone. The nurse realizes further teaching is required if the parents state what?

• A. We will keep our child away from anyone who is ill.
• B. We will be sure to administer the prednisone as ordered.
• C. We will encourage our child to eat a balanced diet, but we will watch his salt intake.
• D. We understand our child will not be able to attend school, so we will arrange for homeschooling.

Correct answer: D

Rationale: Children with MCNS who are in remission can usually attend school and participate in normal activities with precautions to avoid infections. Home schooling may not be necessary, and this indicates a misunderstanding of the condition's management.
