1. Which of the following white blood cell (WBC) counts clearly indicates leukocytosis?

• A. 4,500/mm³
• B. 7,000/mm³
• C. 10,000/mm³
• D. 25,000/mm³

Correct answer: D

Rationale: Leukocytosis is defined as an increase in the total white blood cell count. A normal WBC count typically ranges from 4,500 to 10,000/mm³. A WBC count of 25,000/mm³, as indicated in choice D, is significantly higher than the normal range and clearly indicates leukocytosis.

2. A healthcare professional is preparing to assess a 2-week-old newborn. Which of the following actions should the professional plan to take?

• A. Obtain the newborn's body temperature using a tympanic thermometer.
• B. FACES pain scale.
• C. Auscultate the newborn's apical pulse for 60 seconds.
• D. Measure the newborn's head circumference over the eyebrows and below the occipital prominence.

Correct answer: C

Rationale: Assessing the apical pulse in newborns is important to evaluate their cardiac function. The normal heart rate for a newborn is typically between 100-160 beats per minute. Auscultating the apical pulse for a full 60 seconds allows for an accurate assessment of the newborn's heart rate. This is a crucial component of the newborn assessment to ensure the baby's cardiovascular system is functioning within the expected range.

3. Which chamber of the heart receives oxygenated blood from the lungs?

• A. Left atrium
• B. Right atrium
• C. Left ventricle
• D. Right ventricle

Correct answer: A

Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. This blood is then pumped into the left ventricle before being circulated throughout the body. The right atrium, represented by choice B, actually receives deoxygenated blood from the body through the vena cava. Choices C and D, the left ventricle and right ventricle respectively, are chambers involved in pumping blood out of the heart to the body and lungs, rather than receiving blood from the lungs.

4. What should be done in order to prevent contamination of the environment when making a bed?

• A. Avoid flinging soiled linens
• B. Strip all linens at the same time
• C. Finish both sides at the same time
• D. Embrace soiled linen

Correct answer: A

Rationale: The correct practice to prevent contamination of the environment when making a bed is to avoid flinging soiled linens. Flinging soiled linens can spread contaminants in the environment, leading to potential health risks. By handling soiled linens properly and avoiding flinging them, the risk of contamination is minimized, ensuring a safer and cleaner environment. Stripping all linens at the same time (choice B) may not necessarily prevent contamination if the soiled linens are flung around. Finishing both sides at the same time (choice C) is unrelated to preventing contamination. Embracing soiled linen (choice D) is not hygienic and can lead to spreading contaminants.

5. A client with vision loss is under the care of a nurse. Which of the following actions should the nurse AVOID?

• A. Keep objects in the client's room in the same place
• B. Ensure there is high-wattage lighting in the client's room
• C. Approach the client from the side
• D. Allow extra time for the client to perform tasks

Correct answer: C

Rationale: Approaching a client with vision loss from the side can startle them and may lead to accidents or discomfort. It is important to approach them from the front so they are aware of your presence. Keeping objects in the same place aids in familiarity and reduces the risk of falls. High-wattage lighting enhances visibility for the client. Allowing extra time for tasks accommodates the client's potential slower pace and ensures they can perform tasks safely.
