Exam Cram NCLEX RN Practice Questions

1. A child is admitted to the hospital several days after stepping on a sharp object that punctured her athletic shoe and entered the flesh of her foot. The physician is concerned about osteomyelitis and has ordered parenteral antibiotics. Which of the following actions is done immediately before the antibiotic is started?

A. The admission orders are written.
B. A blood culture is drawn.
C. A complete blood count with differential is drawn.
D. The parents arrive.

Correct answer: B

Rationale: Before starting antibiotics, a blood culture should be drawn to identify the causative organism. This step is crucial as antibiotics may interfere with the identification process. Drawing a complete blood count with differential or writing admission orders are important steps in patient care but are not as critical as obtaining a blood culture to guide appropriate antibiotic therapy. The arrival of the parents is not directly related to the immediate action required before starting antibiotics in this scenario.

2. Which statement by the client with chronic obstructive lung disease indicates an understanding of the major reason for the use of occasional pursed-lip breathing?

A. ''This action of my lips helps to keep my airway open.''
B. ''I can expel more air when I pucker up my lips to breathe out.''
C. ''My mouth doesn't get as dry when I breathe with pursed lips.''
D. ''By prolonging breathing out with pursed lips, the smaller areas in my lungs don't collapse.''

Correct answer: D

Rationale: The correct answer is D. Clients with chronic obstructive pulmonary disease have difficulty exhaling fully due to the weak alveolar walls from the disease process. Pursed-lip breathing helps prevent alveolar collapse by maintaining positive pressure in the airways during exhalation. This is the major reason for using pursed-lip breathing in individuals with chronic obstructive lung disease. Choices A, B, and C are incorrect because they do not directly address the main purpose of pursed-lip breathing, which is to prevent alveolar collapse and improve exhalation in these patients.

3. What is a common error when taking a pulse?

A. Placing the index finger on the radial artery located on the thumb side of a patient's wrist.
B. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure.
C. Counting the pulse for 15 seconds and multiplying the number by four.
D. None of the above will cause errors.

Correct answer: C

Rationale: The correct answer is counting the pulse for 15 seconds and multiplying the number by four. To accurately assess a patient's heart rate or pulse, it is crucial to count the pulse for a full minute. Counting for only 15 seconds and then multiplying by four may result in an inaccurate heart rate calculation. This approach could miss arrhythmias or intermittent pulsations that could be vital indicators of the patient's condition. Placing the index finger on the radial artery, which is located on the thumb side of the patient's wrist, is the correct technique for taking a pulse. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure is a valid observation and not an error in itself. Therefore, the most common error in this scenario is incorrectly calculating the pulse rate by multiplying a 15-second count by four.

4. Which of the following is an example of client handling equipment?

A. Wheelchair
B. Height-adjustable bed
C. Shower chair
D. Call light

Correct answer: B

Rationale: Client handling equipment is designed to reduce stress and workload on healthcare professionals who assist, turn, or lift clients, aiming to decrease the risk of injuries from improper lifting techniques. A height-adjustable bed is a prime example of client handling equipment as it allows healthcare providers to raise the client to a suitable working height, facilitating care provision. Choices A, C, and D are not examples of client handling equipment. While a wheelchair, shower chair, and call light are essential in client care settings, they are not intended to aid in handling and lifting clients.

5. The client is a chronic carrier of infection. To prevent the spread of the infection to other clients or healthcare providers, the nurse emphasizes interventions that do which of the following? (Berman & Snyder, 2012, p. 713)

A. Eliminate the reservoir
B. Block the portal of exit from the reservoir
C. Block the portal of entry into the host
D. Decrease the susceptibility of the host

Correct answer: B

Rationale: To prevent the spread of infection from a chronic carrier, the nurse should focus on blocking the portal of exit from the reservoir, which is the carrier person. By preventing the movement of the organism from the reservoir, the infection can be contained. Eliminating the reservoir is not feasible in this case as the carrier is a chronic carrier. Blocking the portal of entry into the host or decreasing the susceptibility of the host would only impact individual prevention and not the spread from the carrier to others.
