A patient presents with pain in the shoulder. The nurse practitioner knows that there are four rotator cuff muscles. The muscle that initiates abduction movement at the shoulder is known as the:

Correct Answer: A

Rationale: Rationale: The correct answer is A: Supraspinatus. This muscle is responsible for initiating abduction movement at the shoulder joint. It is located on the top of the shoulder blade and assists in lifting the arm away from the body. The other choices, B: Infraspinatus, C: Levator scapulae muscle, and D: Subscapularis, are not involved in initiating abduction movement at the shoulder. Infraspinatus is responsible for external rotation, Levator scapulae muscle elevates the scapula, and Subscapularis assists in internal rotation of the shoulder joint.

Correct Answer: B

Rationale: The correct answer is B: Hirsutism. Hirsutism is the presence of excessive hair growth in a male pattern distribution in women, which is a common sign of hyperandrogenism. Elevated androgen levels can lead to hirsutism in women, especially in conditions like polycystic ovary syndrome. High pitch voice (A) and obesity (D) are not direct indicators of hyperandrogenism. While polycystic ovaries (C) can be associated with hyperandrogenism, the presence of hirsutism is a more specific and direct finding in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Spinal stenosis. The symptoms described suggest neurogenic claudication, which is a hallmark of spinal stenosis. Pain worsening with ambulation and improving with lumbar flexion is characteristic of spinal stenosis due to narrowing of the spinal canal leading to compression of nerves. Ankylosing spondylitis (A) presents with inflammatory back pain and stiffness, not neurogenic claudication. Bursitis (C) involves inflammation of bursae, not typically associated with leg pain and numbness. Cauda equina syndrome (D) presents with sudden-onset severe back pain, urinary retention, and saddle anesthesia, which are not consistent with the described symptoms.

Correct Answer: C

Rationale: Hyperkalemia is associated with diminished renal function because the kidneys play a crucial role in regulating potassium levels in the body. When renal function is impaired, the kidneys may not be able to excrete excess potassium effectively, leading to elevated potassium levels in the blood. - Choice A (Increase BP) is incorrect because hyperkalemia is not directly associated with increased blood pressure. - Choice B (Alpha-blockers) is incorrect as alpha-blockers are not typically linked to hyperkalemia. - Choice D (Loop diuretics) is incorrect as loop diuretics can actually lower potassium levels, not cause hyperkalemia.

Correct Answer: D

Rationale: The correct answer is D: Take it with food. Glucocorticosteroids can irritate the stomach lining, leading to gastritis or ulcers. Taking them with food helps reduce stomach irritation and the risk of gastrointestinal side effects. Crushing it in applesauce (A) or chewing it prior to a high-fat meal (B) can exacerbate stomach irritation. Taking it on an empty stomach (C) can increase the risk of stomach upset and decrease absorption. Therefore, taking it with food (D) is the best option to minimize stomach irritation and improve medication effectiveness.
