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: A

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 1-month-old infant has a head measurement of 34 cm and a chest circumference of 32 cm. Based on the interpretation of these findings, what action would the nurse take?

Correct answer: B

Rationale: In infants, a normal head measurement is approximately 32 to 38 cm, and it is usually around 2 cm larger than the chest circumference. These measurements vary with age; between 6 months and 2 years, both measurements are approximately the same, and after age 2 years, the chest circumference becomes greater than the head circumference. Given that the 1-month-old infant's head measurement is within the typical range and slightly larger than the chest circumference, the nurse should consider these findings normal. There is no indication to refer the infant for further evaluation or to have the parent return for re-evaluation in 2 weeks, as these measurements fall within the expected parameters for a 1-month-old infant.

3. When providing endotracheal suctioning, for how long should the nurse suction the endotracheal tube of an intubated client on a ventilator at a time?

Correct answer: B

Rationale: When providing endotracheal suctioning, the nurse should suction for no longer than ten seconds at a time. Suctioning for longer than ten seconds may cause hypoxia or bronchospasm. Extended suctioning may also place the client at risk of injury to the bronchial and tracheal structures. Choices C and D suggest prolonged suctioning durations that can lead to adverse effects on the client. Choice A, suctioning for five seconds or less, may not be adequate to clear secretions effectively, making choice B the most appropriate duration for safe and efficient suctioning in this scenario.

4. A patient suffering from hyperglycemia would be experiencing:

Correct answer: B

Rationale: Hyperglycemia is a condition characterized by high blood sugar levels. In this state, there is an excess of glucose in the bloodstream. Patients with hyperglycemia are often diagnosed with diabetes. The term 'hyperglycemia' specifically refers to elevated blood sugar levels. Therefore, the correct answer is 'High blood sugar.' Choices A, C, and D are incorrect because hyperglycemia indicates elevated blood sugar levels and not low or normal levels.

5. A patient has come to the office for a blood draw. The patient starts to sweat and is very anxious. Which of the following would be the BEST way to proceed?

Correct answer: B

Rationale: In the scenario where a patient is sweating and anxious, it is important to assess for signs of potential syncope (fainting) while proceeding with the blood draw. If the patient does not exhibit signs of fainting, the phlebotomy procedure can be performed safely. Postponing the procedure may not address the patient's anxiety and inconvenience them. Having the physician draw the blood is not necessary if the phlebotomist can handle the situation effectively.
