1. During auscultation of a patient's heart sounds, the nurse hears an unfamiliar sound. Which action would the nurse take?

A. Ask the patient how he or she is feeling.
B. Document the findings in the patient's record.
C. Wait 10 minutes and auscultate the sound again.
D. Ask another nurse to double-check the finding.

Correct answer: D

Rationale: When encountering an unfamiliar sound during auscultation, it is crucial for the nurse to seek confirmation from another healthcare professional. Asking the patient about their feelings may not provide insight into the unfamiliar sound. Simply documenting the findings without verification may lead to errors in interpretation. Waiting and auscultating again after 10 minutes might delay necessary intervention. Consulting another nurse for a second opinion ensures accurate identification of the unfamiliar sound and appropriate follow-up actions.

2. The client starting an exercise program will progress to walking a 20-minute mile in one month.

A. Client will walk quickly three times a day
B. Client will be able to walk a mile
C. Client will have no alteration in breathing during the walk
D. Client will progress to walking a 20-minute mile in one month

Correct answer: D

Rationale: Outcome statements must be written in behavioral terms and identify specific, measurable client behaviors. They are stated in terms of the client with an action verb that, under identified conditions, will achieve the desired behavior. Choice A lacks specificity and does not mention a target time or goal. Choice B is vague and does not provide a specific target for improvement. Choice C focuses on a negative outcome (no alteration) rather than a positive goal. The correct answer, Choice D, is specific, measurable, and time-bound, making it a suitable outcome statement for a client starting an exercise program.

3. What technique would the nurse use to accurately assess a rectal temperature in an adult?

A. Use a lubricated blunt tip thermometer.
B. Insert the thermometer 2 to 3 inches into the rectum.
C. Leave the thermometer in place for up to 8 minutes if the patient is febrile.
D. Wait 2 to 3 minutes if the patient has recently smoked a cigarette.

Correct answer: A

Rationale: To accurately assess a rectal temperature in an adult, a nurse should use a lubricated rectal thermometer with a short, blunt tip. The thermometer is inserted only 2 to 3 cm (1 inch) into the rectum and left in place for 2 minutes. Choice B is incorrect as inserting the thermometer 2 to 3 inches would be too deep and inaccurate. Choice C is incorrect as leaving the thermometer in place for up to 8 minutes is unnecessary and can cause discomfort. Choice D is incorrect as smoking a cigarette does not impact rectal temperatures.

4. When assessing a pulse, what should be noted?

A. Rate
B. Rate and quality
C. Rate, quality, and fullness
D. Rate, quality, fullness, and regularity

Correct answer: C

Rationale: When assessing a pulse, it is important to note the rate (number of beats per minute), quality (regular or irregular), and fullness (thread and weak or full and bounding). These aspects provide crucial information about the patient's cardiovascular status. Regularity, as mentioned in option D, is not typically assessed during a pulse check and is not necessary for routine pulse assessment. Choice A is too limited as it overlooks important aspects beyond just the rate. Choice B improves by adding quality but still lacks the fullness aspect. Choice C is the most comprehensive and accurate as it includes all three essential aspects for a thorough pulse assessment.

5. Which brain structure serves as the heat-regulating center?

A. Hypothalamus
B. Pituitary Gland
C. Pons
D. Medulla Oblongata

Correct answer: A

Rationale: The correct answer is the Hypothalamus. The hypothalamus is responsible for regulating body temperature, ensuring it stays within a narrow range. Moreover, the hypothalamus controls various essential bodily functions, such as hunger, thirst, and circadian rhythms. Choices B, C, and D are incorrect because the Pituitary Gland primarily produces and releases hormones, the Pons is involved in functions like sleep, respiration, and bladder control, and the Medulla Oblongata controls vital functions like breathing and heart rate, but not body temperature regulation.
