NCLEX RN Predictor Exam

1. When are manual hematocrits done?

A. to monitor anemia
B. by using a microhematocrit tube.
C. to measure the percentage of plasma to cells.
D. All of the above.

Correct answer: D

Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.

2. You are taking care of 7 patients today. One of your residents wants water; another needs help walking to the bathroom; another just stated that they have chest pain; and another is crying because his daughter did not visit him today. Which patient care task is the lowest in terms of priority?

A. The water
B. Help to the bathroom
C. The chest pain
D. The crying person

Correct answer: D

Rationale: The lowest priority patient care task in this scenario is addressing the emotional need of the patient who is crying because his daughter did not visit him today. While emotional support is important, the other needs - providing water, assisting to the bathroom, and addressing chest pain - are physical needs that must take priority as they directly impact the patient's well-being and health. It is crucial to acknowledge and address emotional needs but in this situation, the physical needs of the patients should be addressed first.

3. Which of these is a correctly stated outcome goal written by the nurse?

A. The client will walk 2 miles daily by March 19
B. The client will understand how to give insulin by discharge
C. The client will regain their former state of health by April 1
D. The client achieve desired mobility by May 7

Correct answer: A

Rationale: Outcome goals should be SMART, i.e., Specific, Measurable, Appropriate, Realistic, and Timely. Option A is the only outcome that has a specific behavior (walks daily), with measurable performance criteria (2 miles), and a time estimate for goal attainment (by March 19). Option B lacks specificity in terms of what 'understand how to give insulin' entails, and the timeline is vague ('by discharge'). Option C is not measurable or specific about what 'regain their former state of health' means. Option D does not provide a specific behavior or measurable criteria for 'desired mobility,' and the timeline is the only element that is time-bound.

4. A physician asks you to place the patient with his dorsal side facing the exam table. Which of the following accurately describes how the patient is positioned?

A. The patient is lying prone.
B. The patient is lying supine.
C. The patient is lying in the recovery position.
D. The patient is lying on his stomach.

Correct answer: B

Rationale: When the physician asks for the patient to be placed with their dorsal side facing the exam table, it means the patient should be lying on their back. This position is known as the supine position, where the patient's back is on the table, facing up towards the ceiling. Choice A, 'The patient is lying prone,' is incorrect as the prone position is when the patient is lying face down. Choice C, 'The patient is lying in the recovery position,' is incorrect as the recovery position is a lateral position typically used in first aid. Choice D, 'The patient is lying on his stomach,' is incorrect as it describes the prone position, not the supine position as required in this scenario.

5. What is the most important step that healthcare personnel can take to prevent the transmission of microorganisms in the hospital setting?

A. Wear protective eyewear at all times.
B. Wear gloves whenever in direct contact with patients.
C. Wash hands before and after contact with each patient.
D. Clean the stethoscope with an alcohol swab between patients.

Correct answer: C

Rationale: The most crucial step in preventing the transmission of microorganisms in the hospital setting is proper hand hygiene. Healthcare personnel should wash their hands thoroughly before and after each patient contact to reduce the risk of spreading infections. While cleaning the stethoscope with an alcohol swab between patients is recommended, it is secondary to hand hygiene. Wearing protective eyewear at all times is not necessary for routine patient care unless specifically indicated, and wearing gloves only when in direct contact with patients is important but not as critical as proper handwashing. Therefore, the correct answer is to wash hands before and after contact with each patient.
