What does preload refer to?

Correct Answer: B

Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.

Rationale: The major difference between long-term care and respite centers is that long-term care facilities provide both physical and emotional care on an ongoing, long-term basis. This continuous care is essential for residents who require extended assistance. In contrast, respite centers offer temporary services, providing similar care but for a short-term duration. These short-term services are designed to give family caregivers a break from their daily responsibilities. Choice A is incorrect because both long-term care and respite centers can offer both physical and emotional care, but the key distinction lies in the duration of care provided. Choice B is incorrect as respite centers do not typically offer outpatient services, and the focus is on temporary relief rather than long-term care. Choice D is incorrect as the question clearly highlights a major difference between long-term care and respite centers.

Correct Answer: D

Rationale: After assessing and finding that the vital signs are normal for the patient, the appropriate action would be to document them on the graphic VS form. This form is used to track and record vital sign measurements accurately and consistently. Reporting the normal vital signs to the doctor is not necessary unless there are concerning trends or deviations. Writing the vital signs on a scrap piece of paper is not recommended as it may not be an official or reliable record. Calling the family members is unrelated to the process of documenting and tracking vital signs for the patient.

Correct Answer: D

Rationale: An occupational therapist is the healthcare professional responsible for assessing the needs of individuals, like Penny, regarding assistive devices that aid them in their daily activities. In this case, assistive devices for eating, such as weighted plates and specialized utensils, are crucial for helping Penny regain independence in feeding herself. Physical therapists focus more on mobility and movement, speech therapists on communication and swallowing disorders, and social workers on providing emotional and social support. Therefore, the correct choice is the occupational therapist as they specialize in activities of daily living and promoting independence.
