Vital Signs Assessment Nursing Questions
Question 1 of 5
Which of the following is the primary source of heat in the body?
Correct Answer: B
Rationale: Metabolism is the primary heat source, generating energy via cellular processes, per the answer key. Hormones regulate metabolism but don't produce heat directly. Blood circulation distributes heat, not generates it. Muscles contribute via activity (e.g., shivering), but metabolism is foundational. Nursing texts (e.g., Taylor) emphasize metabolism's role in thermoregulation, critical for understanding fever or hypothermia responses in patient care.
Question 2 of 5
When auscultating a patients abdomen, a nurse notes gurgling sounds. What characteristic of sound would the nurse document?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
Which of the following represents metrorrhagia?
Correct Answer: D
Rationale: Metrorrhagia is defined as bleeding between periods. This is the correct answer as it specifically describes the irregular bleeding pattern associated with metrorrhagia. Choice A refers to the duration between menses, not the timing of bleeding. Choice B relates to the volume of blood, not the timing. Choice C describes infrequent, not irregular, bleeding. Thus, D is the correct choice as it accurately represents metrorrhagia.
Question 4 of 5
How often, according to American Cancer Society recommendations, should a woman undergo a screening breast examination by a skilled clinician?
Correct Answer: C
Rationale: The correct answer is C: Every 3 years. This is based on American Cancer Society recommendations for women aged 20-39 to have a clinical breast examination every 3 years. This frequency ensures regular monitoring without unnecessary burden on the individual. The other choices are incorrect because annual screenings (A) may lead to overdiagnosis and unnecessary procedures, every 2 years (B) may not provide sufficient monitoring, and every 4 years (D) extends the gap between screenings too much, potentially missing early signs of breast cancer. A 3-year interval strikes a balance between regular monitoring and avoiding excessive testing.
Question 5 of 5
Which of the following conditions would produce a hyperresonant percussion note?
Correct Answer: A
Rationale: The correct answer is A: Large pneumothorax. A hyperresonant percussion note indicates excessive air in the chest cavity, leading to increased resonance. In a large pneumothorax, air fills the pleural space, causing the affected lung to collapse and creating a hyperresonant sound upon percussion. Lobar pneumonia (B) typically produces dullness due to consolidation of lung tissue. Pleural effusion (C) results in dullness as well, caused by fluid accumulation in the pleural space. Empyema (D) refers to pus in the pleural space, causing dullness rather than hyperresonance.
