1. The healthcare professional is preparing to use a stethoscope for auscultation. Which statement is true regarding the diaphragm of the stethoscope?

Correct answer: A

Rationale: The diaphragm of the stethoscope is designed for listening to high-pitched sounds like breath, bowel, and normal heart sounds. It should be firmly held against the person's skin to ensure optimal sound transmission, leaving a ring after use. On the other hand, the bell of the stethoscope is ideal for detecting soft, low-pitched sounds such as extra heart sounds or murmurs. Therefore, the diaphragm is not used to block out low-pitched sounds but rather to enhance the detection of high-frequency sounds.

2. During an office visit, the healthcare provider is assessing a patient's skin. What part of the hand and technique would be used to best assess the patient's skin temperature?

Correct answer: B

Rationale: The correct answer is the dorsal surface of the hand. The dorsa (backs) of the hands and fingers are best for determining temperature because the skin is thinner on the dorsal surfaces than on the palms. Fingertips are best for fine, tactile discrimination and not for assessing skin temperature. The ulnar and palmar surfaces of the hands are not as effective for assessing skin temperature as the dorsal surface because they have thicker skin layers.

3. Which of the following constitutes the five rights of medication administration?

Correct answer: C

Rationale: The five rights of medication administration are essential to ensure safe and effective drug delivery to clients. The correct answer includes ensuring the right client receives the right drug at the right dose, via the right route, and at the right time. These elements are crucial to prevent medication errors and ensure optimal therapeutic outcomes. Choice A is incorrect as it includes 'right nurse' which is not part of the five rights of medication administration. Choice B is incorrect as it includes 'right order' which is not part of the five rights. Choice C is incorrect as it includes 'right drug' and 'right route', but it lacks 'right client' and 'right time'. Choice D is incorrect as it includes 'right physician' which is not part of the five rights.

4. Which technique is correct when assessing the radial pulse of a patient?

Correct answer: A

Rationale: When assessing the radial pulse, if the rhythm is irregular, the pulse should be counted for a full minute to get an accurate representation of the pulse rate. In cases where the rhythm is regular, the recommended technique is to palpate for 15 seconds and then multiply by 4 to calculate the beats per minute. This method is more accurate and efficient for normal or rapid heart rates. Palpating for 30 seconds and multiplying by 2 is not as effective, as any error in counting results in a larger discrepancy in the calculated heart rate. Palpating for 2 full minutes is excessive and not necessary for routine pulse assessment. Palpating for 10 seconds and multiplying by 6 is not a standard technique and may lead to inaccuracies, especially in patients with cardiac abnormalities.

5. When performing a physical examination, safety must be considered to protect the examiner and the patient against the spread of infection. Which of these statements describes the most appropriate action the nurse would take when performing a physical examination?

Correct answer: B

Rationale: The most appropriate action for the nurse to take when performing a physical examination is to wash their hands before and after every physical patient encounter. This practice helps prevent the spread of infection. Hands should also be washed after contact with blood, body fluids, secretions, and excretions, and after contact with any equipment contaminated with body fluids. It is crucial to wash hands after removing gloves, even if the gloves appear intact. Choice A is incorrect because washing hands after removing gloves is necessary to ensure thorough hygiene. Choice C is incorrect because hands should be washed before and after every patient encounter, not just before examining each body system. Choice D is incorrect because gloves should be worn when there is potential contact with body fluids, but they do not need to be worn throughout the entire examination.
