Safe and Effective Care Environment NCLEX RN Questions

1. A healthcare professional is employed at a district health department and must spend several hours each day sitting at a desk. Which principle of ergonomics will most likely help them to reduce the risk of injury or pain in this situation?

Correct answer: Adjust the chair height to keep the legs bent at the hips at a 90-degree angle

Rationale: When sitting for prolonged periods, it is important to adjust the height of the chair so that the legs are bent at the hips at a 90-degree angle. This position helps to reduce pressure on the back, legs, and feet, promoting better posture and reducing muscle fatigue. Standing up and moving around at least once every hour is crucial to support circulation and prevent stiffness. Maintaining the position of the computer monitor just below eye level helps reduce strain on the neck and eyes. Resting wrists on the edge of the desk while typing can lead to wrist strain and discomfort, so it is not an ergonomic recommendation for prolonged desk work.

2. A healthcare professional is preparing to administer a dose of platelets to a client. Which of the following actions must the healthcare professional perform before giving the platelets?

Correct answer: Ensure the container with the platelets is intact and not damaged

Rationale: Before administering platelets, it is crucial to check the integrity of the container holding the blood product. An intact container ensures the sterility and safety of the platelets, minimizing the risk of contamination or infection. Option A is incorrect as administering platelets typically does not require starting a new IV line unless indicated for the specific patient. Option C is not the priority as verifying the client's identity can be done at any point during the administration process but is not specific to the platelet transfusion itself. Option D, checking the client's chart for antibiotic use, is not directly related to ensuring the safety of the blood product container.

3. The emergency room nurse admits a child who experienced a seizure at school. The father comments that this is the first occurrence and denies any family history of epilepsy. What is the best response by the nurse?

Correct answer: The seizure may or may not mean your child has epilepsy.

Rationale: The correct response is, 'The seizure may or may not mean your child has epilepsy.' There are various potential causes for a childhood seizure, such as fever, central nervous system conditions, trauma, metabolic alterations, and idiopathic reasons. It's essential not to jump to conclusions about epilepsy based on one seizure. Options A, C, and D provide premature or inaccurate information. Option A may give false reassurance without proper evaluation, option C assumes one seizure guarantees no recurrence, and option D oversimplifies treatment outcomes.

4. Which of the following diseases would require the nurse to wear an N95 respirator as part of personal protective equipment?

Correct answer: D: Measles

Rationale: Infections that require airborne precautions necessitate the use of an N95 respirator, a type of mask that filters particles that are 5 micrograms or smaller. Illnesses that require airborne precautions include Measles, Varicella, Severe Acute Respiratory Syndrome (SARS), and tuberculosis. Measles is a highly contagious airborne disease caused by a virus. It can spread through respiratory droplets when an infected person coughs or sneezes. Wearing an N95 respirator helps prevent the nurse from inhaling these infectious particles. Human immunodeficiency virus, Clostridium difficile enterocolitis, and Vancomycin-resistant enterococcus do not require the use of an N95 respirator as they are not transmitted through the air but have other modes of transmission.

5. What is the likely cause of pericarditis in a young patient?

Correct answer: Infectious processes

Rationale: In younger patients, pericarditis is typically caused by an infection commonly triggered by viruses like the Coxsackie virus, streptococcus, staphylococcus, or Haemophilus influenzae. Infectious processes are the leading cause of pericarditis in younger individuals. Heart failure, Acute MI, and Hypertension are not common causes of pericarditis in young patients. In older adults, acute myocardial infarction (MI) is a more common cause of pericarditis.
