Exam Cram NCLEX RN Practice Questions

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

A. Palpate for 1 minute if the rhythm is irregular.
B. Palpate for 15 seconds and multiply by 4 if the rhythm is regular.
C. Palpate for 2 full minutes to detect any variation in amplitude.
D. Palpate for 10 seconds and multiply by 6 if the rhythm is regular and the patient has no history of cardiac abnormalities.

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.

2. The healthcare provider is preparing to perform a physical assessment. Which statement is true about the inspection phase of the physical assessment?

A. Usually yields little information
B. Takes time and reveals a surprising amount of information
C. May be somewhat uncomfortable for the expert practitioner
D. Requires a thorough examination of the patient's body before proceeding with palpation

Correct answer: B

Rationale: During the inspection phase of a physical assessment, it is essential to take time as it can reveal a significant amount of information. Initially, it may feel uncomfortable for the examiner to focus solely on observing the patient without immediate action. Rushing through inspection is not recommended as it can lead to missing important cues. Train yourself to be thorough during inspection by observing carefully and taking the time needed to gather essential data. Choices A, C, and D are incorrect because inspection typically provides valuable information, may feel uncomfortable at first but is necessary for a comprehensive assessment, and does not involve a quick glance but requires a focused and detailed observation.

3. What is the anatomic structure located in the middle of the heart that separates the right and left ventricles?

A. Septum
B. Sputum
C. Separator
D. None of the above

Correct answer: A

Rationale: The correct answer is the septum. The septum is a structure located in the middle of the heart that separates the right and left ventricles. It plays a crucial role in maintaining the separation between the two ventricles to ensure efficient blood flow. The other choices, 'Sputum' and 'Separator,' are incorrect as they do not refer to the anatomic structure in the heart that serves this specific function. 'Sputum' is a term used to describe phlegm or mucus, not an anatomical structure, and 'Separator' is a generic term that does not specifically identify the cardiac structure mentioned in the question.

4. Which of the following is an anthropometric measurement?

A. Blood pressure
B. Temperature
C. Pulse Rate
D. Weight

Correct answer: D

Rationale: Anthropometric measurements relate to the size, weight, and proportions of the human body. Weight is a key anthropometric measurement as it directly reflects body mass, making it the correct choice. Blood pressure, temperature, and pulse rate are physiological measurements that do not specifically pertain to body size or proportion, hence making them incorrect choices in the context of anthropometric measurements.

5. For a healthcare worker under normal conditions with unsoiled hands, effective hand hygiene between patients requires which of the following?

A. At least a 15-second scrub with plain soap and water
B. At least a 23-minute scrub with an antimicrobial soap
C. Use of an alcohol-based antiseptic hand-rub
D. Wearing a mask when scrubbing

Correct answer: C

Rationale: Effective hand hygiene between patients for a healthcare worker with unsoiled hands involves using an alcohol-based antiseptic hand rub. This method is sufficient for cleaning hands that are not visibly soiled. The use of an antimicrobial soap or a prolonged scrubbing time is unnecessary and not recommended in this scenario. Wearing a mask is not required for routine hand hygiene and does not contribute to effective hand cleaning.
