The healthcare provider sustains a needle puncture that requires HIV prophylaxis. Which of the following medication regimens should be used?
- A. an antibiotic such as Metronidazole and a protease inhibitor (Saquinavir)
- B. two non-nucleoside reverse transcriptase inhibitors
- C. one protease inhibitor such as Nelfinavir
- D. two protease inhibitors
Correct Answer: B
Rationale: In the scenario of a needle puncture requiring HIV prophylaxis, the CDC recommends initiating treatment with two non-nucleoside reverse transcriptase inhibitors, unless there is drug resistance. This regimen is preferred over other options such as a single protease inhibitor or two protease inhibitors due to its effectiveness and safety profile in this specific context. Non-nucleoside reverse transcriptase inhibitors are commonly used in post-exposure prophylaxis due to their activity against HIV and lower risk of resistance development compared to other antiretroviral drug classes.

After delivery, a newborn undergoes an Apgar assessment. What does this scoring system evaluate?
- A. heart rate, respiratory effort, color, muscle tone, reflex irritability
- B. heart rate, bleeding, cyanosis, edema
- C. bleeding, reflex, edema
- D. respiratory effort, heart rate, seizures
Correct Answer: B
Rationale: The Apgar scoring system, developed by Virginia Apgar, an anesthesiologist, evaluates newborns based on five criteria: heart rate, respiratory effort, color, muscle tone, and reflex irritability. These parameters provide a quick and simple assessment of a newborn's overall condition and the need for immediate medical attention. Choices B, C, and D are incorrect as they do not encompass the essential elements evaluated by the Apgar scoring system.
Which of the following statements describes the purpose of client restraint?
- A. Restraints are a nursing measure used to maintain client control.
- B. Restraints are an emergency intervention taken as a last resort to protect a client from imminent danger.
- C. Restraints are a therapeutic measure designed to positively reinforce client behavior.
- D. Restraints are an emergency measure that can only be taken by a nurse under the direct supervision of a physician.
Correct Answer: B
Rationale: The correct answer is B. Restraints are used as an emergency intervention when all other options to protect a client from imminent danger have been exhausted. Restraints should only be used as a last resort to ensure the safety of the client and others. Choices A, C, and D are incorrect because restraints are not used to maintain control, reinforce behavior, or are exclusively taken under direct physician supervision. It is crucial to remember that restraint use should always be based on careful assessment, documentation, and adherence to legal and ethical guidelines.
A syringe pump is a type of electronic infusion pump used to infuse fluids or medications directly from a syringe. This device is commonly used for:
- A. solutions administered in obstetrics.
- B. dilute antibiotics.
- C. large volumes of IV solutions.
- D. the neonatal and pediatric populations.
Correct Answer: D
Rationale: The correct answer is 'the neonatal and pediatric populations.' Syringe pumps are commonly used in neonatal and pediatric populations because they allow for precise infusion of small volumes of medications or fluids at controlled rates. This is crucial for ensuring safety and accuracy in these delicate populations. Choice A is incorrect because syringe pumps are not limited to obstetrics; they are used in various healthcare settings. Choices B and C are incorrect because syringe pumps are not typically used for dilute antibiotics or large volumes of IV solutions. Instead, they are preferred for delivering small volumes accurately, making them ideal for neonatal and pediatric care.
A 4-year-old client is unable to go to sleep at night in the hospital. Which nursing intervention best promotes sleep for the child?
- A. turning off the room light and closing the door
- B. engaging the child in calming activities before bedtime
- C. identifying the child's home bedtime rituals and following them
- D. encouraging relaxation techniques like deep breathing exercises
Correct Answer: C
Rationale: For a 4-year-old client struggling to sleep in the hospital, the best nursing intervention is to identify the child's home bedtime rituals and follow them. Preschool-age children often have specific bedtime routines that provide comfort and promote sleep. This familiarity can help create a sense of security in an unfamiliar hospital environment. Choice A, turning off the room light and closing the door, may increase the child's fear of the dark and being alone. Choice B, engaging the child in calming activities before bedtime, is a better choice than tiring them with play exercises. Choice D, encouraging relaxation techniques like deep breathing exercises, although helpful, may not be as effective as following the child's familiar bedtime routines.
Which of the following neurological disorders is characterized by writhing, twisting movements of the face and limbs?
- A. epilepsy
- B. Parkinson's
- C. multiple sclerosis
- D. Huntington's chorea
Correct Answer: D
Rationale: Huntington's chorea is characterized by writhing, twisting movements of the face and limbs, known as chorea. This disorder is caused by a genetic mutation affecting specific brain cells. Epilepsy presents with seizures, Parkinson's with tremors and rigidity, and multiple sclerosis with central nervous system issues. The specific description of writhing and twisting movements aligns with Huntington's chorea, making it the correct answer. Choices A, B, and C are incorrect as they describe different neurological disorders with distinct symptoms that do not match the writhing, twisting movements characteristic of Huntington's chorea.
