1. When auscultating the blood pressure of a 25-year-old patient, the nurse notices that the phase I Korotkoff sounds begin at 200 mm Hg. At 100 mm Hg, the Korotkoff sounds muffle. At 92 mm Hg, the Korotkoff sounds disappear. How should the nurse record this patient's blood pressure?

A. 200/92
B. 200/100
C. 100/200/92
D. 200/100/92

Correct answer: A

Rationale: When auscultating blood pressure, it is crucial to note the points at which Korotkoff sounds change. In adults, the last audible sound indicates the diastolic pressure. In this case, the Korotkoff sounds muffle at 100 mm Hg and disappear at 92 mm Hg. Therefore, the blood pressure should be recorded as systolic/diastolic, which is 200/92. Choices B, C, and D are incorrect because they do not reflect the correct points where the Korotkoff sounds change during blood pressure measurement.

2. What is the flap of tissue that covers the trachea upon swallowing called?

A. Epidermis
B. Endocardium
C. Epiglottis
D. Epistaxis

Correct answer: C

Rationale: The correct answer is C: Epiglottis. The epiglottis is a flap of tissue that covers the trachea when swallowing to prevent food or liquid from entering the airway. Choice A, Epidermis, is the outer layer of the skin and is not related to the trachea. Choice B, Endocardium, is the inner lining of the heart chambers and is also unrelated to the trachea. Choice D, Epistaxis, refers to a nosebleed and is not the correct term for the tissue covering the trachea.

3. Which statement best describes evidence-based practice?

A. Reading and analyzing research reports to determine their implementation in nursing practice
B. Collecting data to evaluate the efficiency of nursing practice in delivering quality care
C. Monitoring unit practices to ensure adherence to Joint Commission standards
D. Using the most effective, current, and applicable information to guide nursing care for the best outcomes

Correct answer: D

Rationale: Evidence-based practice involves utilizing the most effective, current, and relevant information to inform nursing care decisions for optimal client outcomes. While research reports and data collection are important components of evidence-based practice, the essence lies in integrating all available information to determine the best course of action. Monitoring compliance with standards, as described in choices A and C, is essential for quality assurance but does not capture the comprehensive nature of evidence-based practice.

4. A nurse is caring for newborn infants in a nursery when a man enters the area to take his baby back to the room. The man does not have an identification bracelet, and the nurse does not recognize him. What is the next action of the nurse?

A. Call security and ask them to escort the man out of the nursery
B. Ask the man to wait and check the infant's chart
C. Ask the man to return to his room and bring an identification band
D. Allow the man to take the baby to his room

Correct answer: C

Rationale: The safety of infants in newborn nurseries is maintained by requiring parents to wear identification bracelets to identify themselves as the rightful parents. This practice minimizes the risk of mistakenly allowing an unauthorized individual to take a baby. In this scenario, since the nurse does not recognize the man and he lacks an identification bracelet, the appropriate action is to ask him to return to his room and bring the identification band. This step ensures the proper identity verification before allowing the man to take the baby. Calling security without first verifying the man's identity may escalate the situation unnecessarily. Checking the infant's chart alone does not confirm the man's identity. Allowing the man to take the baby without proper verification poses a safety risk to the infant.

5. A client with an enlarged prostate is having trouble starting his flow of urine when using the bathroom. Another name for this condition is:

A. Hesitancy
B. Oliguria
C. Retention
D. Urgency

Correct answer: A

Rationale: Urinary hesitancy occurs when a client has difficulty starting a flow of urine while using the bathroom. Hesitancy may be due to physiological factors, such as obstruction from an enlarged prostate, or due to psychological factors, such as anxiety or embarrassment. Oliguria refers to decreased urine output, retention is the inability to empty the bladder fully, and urgency is the sudden and strong need to urinate.
