Assessing Vital Signs Questions
Question 1 of 5
Kienböck's disease involves which of the following features?
Correct Answer: D
Rationale: Kienböck's disease is osteonecrosis of the lunate bone. This occurs due to disrupted blood supply, leading to lunate collapse and wrist pain. Option D is correct as it directly relates to the pathology of Kienböck's disease. Options A, B, and C are incorrect as they do not describe the specific feature associated with Kienböck's disease. Osteonecrosis of the scaphoid (Option A) is more commonly seen in Preiser's disease, while Pencil-in-cup deformities (Option B) are typically associated with psoriatic arthritis. Heberden's and Bouchard's nodules (Option C) are seen in osteoarthritis of the fingers, not in Kienböck's disease.
Question 2 of 5
When listening to a patient's breath sounds, the nurse is unsure of a sound that is heard. The nurse's next action should be to:
Correct Answer: C
Rationale: The correct answer is C: Validate the data by asking a coworker to listen to the breath sounds. This is the best course of action as it involves seeking a second opinion to confirm the unclear sound heard, ensuring accuracy in assessment. Notifying the physician immediately (A) may be premature without validation. Documenting the sound (B) without confirmation can lead to inaccurate documentation. Assessing again in 20 minutes (D) may delay necessary intervention if the sound is significant. Asking a coworker to validate the data (C) allows for immediate clarification and ensures accurate assessment.
Question 3 of 5
Barriers to incorporating EBP include:
Correct Answer: A
Rationale: Step 1: Evidence-based practice (EBP) requires nurses to critically evaluate research studies. Step 2: To incorporate EBP, nurses need research skills to assess the quality of studies. Step 3: Lack of research skills hinders nurses from effectively utilizing EBP. Step 4: Choice A is correct as it directly addresses a barrier to incorporating EBP. Summary: Choices B, C, and D are incorrect as they do not specifically relate to the need for research skills in evaluating the quality of research studies, which is essential for implementing EBP.
Question 4 of 5
Which respiratory disease causes a restrictive, parenchymal pattern of illness?
Correct Answer: C
Rationale: The correct answer is C: Sarcoidosis. Sarcoidosis is a respiratory disease characterized by granulomatous inflammation in the lung parenchyma, leading to a restrictive pattern of lung function. This results in decreased lung volume and impaired gas exchange. Myasthenia gravis (A) is a neuromuscular disorder, not a respiratory disease. Asthma (B) is characterized by reversible airway obstruction, not a restrictive pattern. Ankylosing spondylitis (D) primarily affects the spine and joints, not the lungs. Therefore, the correct choice is C based on the specific pathological and clinical features of sarcoidosis.
Question 5 of 5
A light is pointed at a patient's pupil, which contracts. It is also noted that the other pupil contracts as well, though it is not exposed to bright light. Which of the following terms describes this latter phenomenon?
Correct Answer: B
Rationale: The correct answer is B: Consensual reaction. This phenomenon occurs when shining light into one eye causes both pupils to constrict due to the pupillary light reflex. The optic nerves from both eyes converge in the brain, leading to the consensual reaction in the non-illuminated eye. Direct reaction (A) refers to the pupil directly exposed to light. Near reaction (C) is associated with changes in pupil size in response to focusing on near objects. Accommodation (D) is the process of adjusting the lens shape for near vision and is not directly related to pupillary constriction.
