Erectile dysfunction is
- A. A normal change of aging
- B. Treated with medication
- C. Incurable
- D. An inflammation of the testes
Correct Answer: B
Rationale: The correct answer is B because erectile dysfunction is a medical condition that can be effectively treated with medication. Erectile dysfunction is not a normal part of aging (choice A), as it can occur at any age. It is also not incurable (choice C), as there are various treatment options available. Additionally, erectile dysfunction is not related to inflammation of the testes (choice D), which is a separate medical issue. Therefore, choice B is the correct answer as it aligns with the common treatment approach for erectile dysfunction.

The ______ is the outer layer of the skin which is composed of dead cells.
- A. Integument
- B. Epidermis
- C. Dermis
- D. Melanocyte
Correct Answer: B
Rationale: The correct answer is B: Epidermis. The epidermis is the outer layer of the skin and is primarily composed of dead cells. It acts as a protective barrier for the body. The other choices are incorrect because: A) Integument is a broader term referring to the entire skin and its appendages. C) Dermis is the layer beneath the epidermis, containing living cells and providing structural support. D) Melanocyte is a cell responsible for producing melanin in the skin, not the outer layer itself.

Which of the following medication types are used to decrease the workload of the heart by blocking sympathetic stimulation of receptors that work on the SA node and myocardial cells, thus decreasing the force of myocardial contraction and directly reducing a patient's heart rate?
- A. Alpha-adrenergic agents
- B. Beta-blockers
- C. Calcium-channel blockers
- D. Sodium-channel blockers
Correct Answer: B
Rationale: The correct answer is B: Beta-blockers. Beta-blockers decrease the workload of the heart by blocking the sympathetic stimulation of beta-adrenergic receptors in the heart. This action results in a decrease in heart rate and the force of myocardial contraction. By blocking these receptors, beta-blockers reduce the impact of adrenaline and other stress hormones on the heart, leading to a decrease in the heart's workload.
A: Alpha-adrenergic agents primarily work on alpha-adrenergic receptors and do not have the same effect on decreasing the workload of the heart.
C: Calcium-channel blockers work by blocking calcium channels in the heart and blood vessels, leading to vasodilation and decreased contractility of the heart. While they can reduce the heart's workload, they do not primarily target sympathetic stimulation of receptors working on the SA node and myocardial cells.
D: Sodium-channel blockers primarily affect the conduction of electrical impulses in the heart and are used for different purposes, such as
Which one following statements on transitional care is true:
- A. There is no need for transitional care for patients discharged to a nursing home as there are healthcare professionals on site
- B. Transitional care starts when a patient is at the next destination of care
- C. There is no time limit for the duration of transitional care
- D. Transitional care is most impactful in high-risk patients with complex medical issues
Correct Answer: D
Rationale: Transitional care is critical for high-risk, complex patients to prevent readmissions. Nursing homes still require transitional planning, it starts before discharge, and has a defined duration, making D the most accurate.
When transferring a resident who has a weak side,
- A. The weaker side moves first
- B. The stronger side moves first
- C. The strong side and weak side move at the same time
- D. It does not matter which side moves first
Correct Answer: B
Rationale: The correct answer is B because when transferring a resident with a weak side, it is important to move the stronger side first to provide better support and stability. By moving the stronger side first, you can ensure proper weight distribution and reduce the risk of falls or injuries. This approach also helps prevent the weaker side from bearing too much weight or strain.
Choice A is incorrect because moving the weaker side first may compromise the resident's safety and stability. Choice C is incorrect as it can lead to imbalance and increase the risk of falls. Choice D is incorrect because the sequence of movement does matter to ensure a safe transfer for both the resident and the caregiver.
