Which technique should the nurse use to determine the presence of crepitus during a physical examination?
- A. Percussion
- B. Auscultation
- C. Palpation
- D. Auscultation
Correct Answer: A
Rationale: The correct technique to determine the presence of crepitus during a physical examination is palpation. Crepitus is a crackling or grating sensation that is felt when there is air trapped in the subcutaneous tissue. Palpation involves using the hands to feel for abnormalities such as crepitus. Percussion involves tapping on the body to produce sounds that can help assess underlying structures, not to determine the presence of crepitus. Auscultation is listening to sounds within the body using a stethoscope, which is not relevant for detecting crepitus.

Which fetal heart monitor pattern can indicate cord compression?
- A. variable decelerations
- B. early decelerations
- C. bradycardia
- D. tachycardia
Correct Answer: A
Rationale: The correct answer is A: variable decelerations. Variable decelerations are abrupt decreases in fetal heart rate that vary in depth, duration, and timing, which can indicate cord compression. The variability in these decelerations suggests that the umbilical cord is being compressed intermittently.
Early decelerations (B) are usually caused by head compression during contractions and mirror the contractions, not indicating cord compression. Bradycardia (C) is a slow heart rate, which can be caused by various factors but is not specific to cord compression. Tachycardia (D) is a fast heart rate, which can also be caused by various factors but is not typically associated with cord compression.
What is the most important intervention for a client with a wound infection?
- A. Administer antibiotics
- B. Apply a cold compress
- C. Apply heat to the wound
- D. Administer IV fluids
Correct Answer: A
Rationale: The correct answer is A: Administer antibiotics. Antibiotics are crucial in treating wound infections as they target and eliminate the infection-causing bacteria, preventing the infection from spreading and promoting healing. Applying a cold compress (choice B) or heat (choice C) may provide temporary relief but do not address the underlying infection. Administering IV fluids (choice D) may be necessary for hydration, but it does not directly treat the infection. Antibiotics directly target the infection, making it the most important intervention for a client with a wound infection.
A nurse is teaching a patient with asthma about managing triggers. Which of the following statements by the patient indicates proper understanding?
- A. I should avoid environmental allergens and cold air.
- B. I should take over-the-counter medications to control my symptoms.
- C. I should smoke to relieve stress and manage my symptoms.
- D. I should only use my inhaler when I feel short of breath.
Correct Answer: A
Rationale: The correct answer is A because avoiding environmental allergens and cold air can help prevent asthma attacks. This shows the patient understands the importance of managing triggers. Choice B is incorrect because over-the-counter medications may not be sufficient for asthma management. Choice C is incorrect because smoking can worsen asthma symptoms. Choice D is incorrect because using the inhaler only when feeling short of breath is not a proactive approach to managing asthma triggers.
What is the most appropriate action when a parent crosses their arms and legs during an interview?
- A. Just changing positions
- B. More comfortable in this position
- C. Tired and needs a break
- D. Uncomfortable talking about his son's treatment
Correct Answer: D
Rationale: The correct answer is D because crossing arms and legs can indicate defensiveness or discomfort, which may suggest the parent is uneasy discussing their son's treatment. This nonverbal cue could signal a need for empathy and sensitivity in communication. Choice A is incorrect as it overlooks the significance of body language. Choice B assumes comfort without considering the context. Choice C assumes tiredness without considering other possibilities. Understanding body language cues can help in building rapport and addressing concerns effectively.
Which medication should be administered first for a client with acute asthma exacerbation?
- A. Albuterol
- B. Epinephrine
- C. Levalbuterol
- D. IV corticosteroids
Correct Answer: A
Rationale: Step-by-step rationale for choosing Albuterol as the correct answer:
1. Albuterol is a rapid-acting bronchodilator that provides immediate relief by relaxing the airway muscles during asthma exacerbation.
2. It is the first-line medication recommended by guidelines for acute asthma attacks due to its quick onset of action.
3. Albuterol helps in opening the airways, improving airflow, and relieving symptoms like shortness of breath and wheezing.
4. Epinephrine is not the first choice for asthma exacerbation as it can have more systemic side effects.
5. Levalbuterol is a similar medication to Albuterol but may not be as widely available or cost-effective.
6. IV corticosteroids are important for long-term control but take longer to show effects, making them less suitable as the initial treatment for acute exacerbation.
