Correct Answer: C

Rationale: When a patient laughs due to anxiety during an EKG, it is likely to cause tachycardia, which is a rapid heart rate. This increased heart rate can lead to poor EKG graph quality as the electrical signals from large moving muscles can interfere with data collection from the chest leads. Therefore, in this scenario, the EKG is expected to show tachycardia with poor graph quality. Choices A, B, and D are incorrect because a patient laughing out of anxiety is more likely to result in an increased pulse rate (tachycardia) rather than a decreased pulse rate (bradycardia) or a normal EKG.

Correct Answer: B

Rationale: To take an apical pulse accurately, you should place the stethoscope over the heart and count the number of beats per minute. This method provides a precise assessment of the heart rate. While listening for irregular beats is essential for assessing the heart's rhythm, the primary objective of taking an apical pulse is to determine the heart rate. Choices C and D are incorrect because the apical pulse is not taken at the wrist; instead, it is obtained by auscultating at the apex of the heart, usually at the point where the fifth intercostal space meets the midclavicular line.

Correct Answer: D

Rationale: The correct answer is 'Never demonstrated.' Despite the patient sleeping a total of 6 hours daily, it is not achieved in one uninterrupted session at night as per the desired outcome. The patient's habit of taking a 2-hour afternoon nap also affects the evaluation. Therefore, the outcome should be evaluated as 'Never demonstrated.' Choice A, 'Consistently demonstrated,' is incorrect because the desired outcome of sleeping for a minimum of 5 hours nightly in one session is not met. Choice B, 'Often demonstrated,' is incorrect as the patient's sleep pattern does not consistently align with the desired outcome. Choice C, 'Sometimes demonstrated,' is also incorrect as the patient's sleep pattern does not meet the specific criteria set in the desired outcome.

Correct Answer: C

Rationale: The correct action to help prevent a fire in a healthcare setting is to notify visitors or post signs indicating that oxygen is in use in certain areas. Oxygen is a combustible material, and awareness of its presence is crucial to prevent fire hazards. By informing all individuals in the facility about the use of oxygen through clear signs or notifications, the risk of improper use and potential fire accidents can be minimized. Choice A is incorrect because using an adaptor when plugging in client equipment is not directly related to fire prevention. Choice B is also incorrect as marking faulty equipment and using it until inspection does not directly address fire prevention. Choice D is not a recommended action for fire prevention; storing extra equipment with supplies does not address the specific fire risk associated with oxygen use.

Correct Answer: B

Rationale: The correct answer is 'lateral.' The Sims' position is characterized by the patient lying on their side with the upper knee flexed and the upper arm positioned in front of the body. This is similar to the lateral position where the patient is also lying on their side. The prone position (choice A) is when the patient lies face down, the supine position (choice C) is when the patient lies face up, and Fowler's position (choice D) is a seated position with the head of the bed elevated at a 45-90 degree angle. Therefore, the lateral position is the most similar to the Sims' position as both involve the patient lying on their side.
