Correct Answer: A

Rationale: The correct answer is A: Anticholinesterase drugs. These drugs increase acetylcholine levels at neuromuscular junctions, helping improve muscle strength in myasthenia gravis. Adrenergic drugs (B) and beta-blocker drugs (D) are not typically used to treat muscle weakness in myasthenia gravis. Anticholinergic drugs (C) can worsen symptoms by blocking acetylcholine receptors, making them an inappropriate choice for this condition.

Correct Answer: D

Rationale: The correct answer is D: Hyperparathyroidism. This disorder is characterized by excessive secretion of parathyroid hormone, leading to increased calcium levels in the blood. The symptoms described in the question - bone pain, weakness, irritability, and depression - are all associated with hypercalcemia, a common manifestation of hyperparathyroidism. Additionally, the client's anorexia and increased urination can be attributed to the effects of hypercalcemia on the gastrointestinal and renal systems. Diabetes mellitus (choice A) involves high blood sugar levels and is not associated with the symptoms described. Hypoparathyroidism (choice B) is characterized by low levels of parathyroid hormone and calcium, leading to different symptoms such as muscle cramps and seizures. Diabetes insipidus (choice C) is a disorder of water balance characterized by excessive thirst and urination, not the symptoms presented in the question.

Correct Answer: A

Rationale: The correct answer is A: Identify factors interfering with goal achievement. This is the priority action because it focuses on understanding what caused the patient to fall despite the goal of preventing falls. By identifying the factors interfering with goal achievement, the nurse can make necessary adjustments to the care plan to prevent future falls. Choice B is incorrect because counseling the nursing assistive personnel and removing the fall risk sign does not address the root cause of the fall. Choice C is incorrect because shifting responsibility to the charge nurse for documentation does not address the immediate need to assess and address the factors contributing to the fall. Choice D is incorrect because documenting the fall is important but not the priority when the immediate concern is understanding why the fall occurred.

Correct Answer: C

Rationale: The correct answer is C because subjective data refers to information provided by the patient based on their feelings, perceptions, and experiences. In this case, the patient describing excitement about discharge is subjective data as it reflects the patient's emotional state. The other choices, A, B, and D, are considered objective data because they are observable and measurable by the nurse. The patient's temperature can be measured (A), the wound appearance can be visually assessed (B), and the patient pacing the floor is an observable behavior (D). Therefore, these choices are not subjective data.

Correct Answer: A

Rationale: The correct answer is A: Phagocytosis. Macrophages and neutrophils are both types of phagocytes responsible for engulfing and digesting pathogens such as bacteria. This process helps in clearing infections and maintaining immune homeostasis. Summary: - Choice B (Complement fixation) is incorrect as it refers to a process where complement proteins bind to pathogens to enhance their removal by phagocytes. - Choice C (Antibody production) is incorrect as macrophages and neutrophils do not produce antibodies. They mainly rely on phagocytosis for pathogen clearance. - Choice D (Suppression of autoimmunity) is incorrect as these cells are involved in innate immunity and do not play a direct role in regulating autoimmunity.
