NCLEX RN Exam Prep

1. What does preload refer to?

Correct answer: B

Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.

2. The client starting an exercise program 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. 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.

4. A client is preparing to irrigate a colostomy. Which of the following situations is a contraindication for this type of irrigation?

Correct answer: C

Rationale: When a client with a colostomy is preparing for irrigation, it is essential to consider contraindications that could pose risks or worsen the client's condition. Diverticulitis is a contraindication for colostomy irrigation because the inflamed diverticula could be further irritated by the flushing action during irrigation, potentially leading to complications. An incontinent ostomy, irregular bowel routine, or presence of fecal material in the colostomy bag are not specific contraindications for irrigation and can be managed through appropriate techniques and interventions.

5. A client is complaining of pain that starts in the shoulder and travels down the length of his arm. This type of pain is referred to as:

Correct answer: C

Rationale: Radiating pain is the correct term for pain that originates in one part of the body and extends to other related areas. In this scenario, the pain starting in the shoulder and traveling down the arm describes radiating pain. Referred pain (Choice A) is pain felt at a site different from the actual origin of the pain. Superficial pain (Choice B) is pain that arises from the skin or tissues just beneath it. Precipitating pain (Choice D) refers to pain that is triggered by specific actions or events, not the characteristic described in the question.
