1. What are Korotkoff sounds?

Correct answer: B

Rationale: Korotkoff sounds are the sounds that occur when blood flows in an artery that has been temporarily compressed during a blood pressure measurement. These sounds result from the vibration of blood against the artery walls as the pressure cuff is released. There are five distinct phases of Korotkoff sounds, which healthcare providers are trained to identify during blood pressure assessment. The correct answer, choice B, accurately describes the nature of Korotkoff sounds and how they are generated. Choices A, C, and D are incorrect because Korotkoff sounds are not specific to diastole, not limited to skilled cardiologists, and categorized into five phases, not six.

2. You have been assigned to take an apical pulse for one of the patients on the nursing unit. How will you do this?

Correct answer: B

Rationale: To take an apical pulse accurately, you should place the stethoscope over the heart and count the number of beats per minute. This method provides a precise assessment of the heart rate. While listening for irregular beats is essential for assessing the heart's rhythm, the primary objective of taking an apical pulse is to determine the heart rate. Choices C and D are incorrect because the apical pulse is not taken at the wrist; instead, it is obtained by auscultating at the apex of the heart, usually at the point where the fifth intercostal space meets the midclavicular line.

3. After change-of-shift report, which patient should the nurse assess first?

Correct answer: D

Rationale: The patient with lung cancer and tracheal deviation after a subclavian catheter insertion should be assessed first. Tracheal deviation can indicate tension pneumothorax, a life-threatening condition that requires immediate intervention to prevent inadequate cardiac output or hypoxemia. While the other patients also need assessment, the potential for tension pneumothorax in the patient with tracheal deviation necessitates urgent attention to prevent complications.

4. Which of these techniques uses the sense of touch to assess texture, temperature, moisture, and swelling when assessing a patient?

Correct answer: A

Rationale: The correct answer is Palpation. Palpation involves using the sense of touch to assess texture, temperature, moisture, and swelling in a patient. This technique allows the nurse to feel for abnormalities and changes in the patient's tissues. Inspection primarily relies on visual assessment, while percussion involves tapping on the body to produce sounds and assess underlying structures. Auscultation, on the other hand, involves listening to sounds within the body using a stethoscope. Therefore, in the context of assessing texture, temperature, moisture, and swelling, palpation is the most appropriate technique.

5. When is a physician likely to assess turgor?

Correct answer: C

Rationale: Skin turgor is assessed when dehydration is suspected. To evaluate skin turgor, a physician pinches the skin and observes how quickly it returns to its normal position. If the skin stays folded for an extended period, it indicates dehydration. Assessing turgor helps determine a patient's hydration status. Choice A is incorrect because skin turgor is not used to assess iron deficiency. Choice B is incorrect as turgor is not related to heart and lung issues, but rather hydration status. Choice D is incorrect as turgor assessment is relevant when dehydration is suspected.
