Nursing Elites

1. Assessment of the client with an arteriovenous fistula for hemodialysis should include:

• A. inspection for visible pulsations.
• B. palpation of thrill.
• C. percussion for dullness.
• D. auscultation of blood pressure.

Correct answer: B

Rationale: The correct answer is to palpate for a thrill. A thrill should be present in a functioning arteriovenous fistula (AVF) and indicates good blood flow. The client should be educated to check for this sensation daily at home to monitor the AVF's patency. Visible pulsations are not typically observed in an AVF. Percussion for dullness does not provide relevant information about the AVF. Auscultation of blood pressure is not a standard practice in assessing an AVF. However, auscultation of the AVF for a bruit, a sound indicating turbulent blood flow, is crucial in evaluating the AVF's patency.

2. Which of the following injuries, if demonstrated by a client entering the Emergency Department, is the highest priority?

• A. open leg fracture
• B. open head injury
• C. stab wound to the chest
• D. traumatic amputation of a thumb

Correct answer: C

Rationale: A stab wound to the chest might result in lung collapse and mediastinal shift that, if untreated, could lead to death. Treatment of an obstructed airway or a chest wound is a higher priority than hemorrhage. The principle of ABC (airway, breathing, and circulation) prioritizes care decisions. In this scenario, the stab wound to the chest poses the highest risk to the client's life as it can lead to severe complications such as lung collapse and mediastinal shift. Addressing this injury promptly is crucial to prevent further harm or potential fatality. Open leg fracture, open head injury, and traumatic amputation of a thumb, while serious, do not pose an immediate life-threatening risk compared to a stab wound to the chest.

3. What are the side effects of first-generation over-the-counter (OTC) antihistamines like diphenhydramine (Benadryl) and hydroxyzine (Atarax) in infants and children?

• A. Reye's syndrome.
• B. cholinergic effects.
• C. paradoxical CNS stimulation.
• D. nausea and diarrhea.

Correct answer: C

Rationale: The correct answer is paradoxical CNS stimulation. First-generation OTC antihistamines, such as diphenhydramine and hydroxyzine, can lead to paradoxical CNS stimulation in infants and children. This phenomenon is characterized by symptoms like excitement, euphoria, restlessness, and confusion, rather than the expected sedative effect. Due to this unexpected response, these antihistamines are used less frequently in pediatric populations. Reye's syndrome is a rare systemic response to a virus and is not a side effect of antihistamines. First-generation OTC antihistamines do not typically exhibit cholinergic effects. Nausea and diarrhea are uncommon side effects of these antihistamines and are less commonly observed than paradoxical CNS stimulation.

4. The nurse is caring for a client with hyperemesis gravidarum. What is the most likely electrolyte imbalance?

• A. Hypocalcemia
• B. Hypomagnesemia
• C. Hyponatremia
• D. Hypokalemia

Correct answer: D

Rationale: In hyperemesis gravidarum, where the client experiences severe nausea and vomiting, the most likely electrolyte imbalance is hypokalemia. Potassium is abundant in the stomach, and excessive vomiting leads to potassium loss. Hypocalcemia (Choice A) is not typically associated with hyperemesis gravidarum. Hypomagnesemia (Choice B) and Hyponatremia (Choice C) are less likely to occur compared to hypokalemia in this condition.

5. When choosing a needle gauge for an intramuscular injection in a 12-year-old boy, which of the following gauges would you choose?

• A. 27 gauge
• B. 25 gauge
• C. 22 gauge
• D. 20 gauge

Correct answer: C

Rationale: The correct answer is 22 gauge. A 22-gauge needle is recommended for school-age children, toddlers, and adolescents due to their muscle mass and tolerance. In infants, a smaller gauge (23-25) is preferred as their muscles are less developed and more sensitive. Choice A, 27 gauge, is too thin for an intramuscular injection in a 12-year-old boy. Choice B, 25 gauge, is more suitable for infants than for a 12-year-old. Choice D, 20 gauge, is too thick and not typically used for intramuscular injections in children.
