Correct Answer: A

Rationale: The correct answer is A: The client’s breathing will become easier. Epinephrine is the first-line treatment for anaphylaxis as it helps to reverse the severe respiratory symptoms. By administering epinephrine, it causes bronchodilation, which helps improve breathing by opening up the airways. Choices B, C, and D are incorrect. B is incorrect because epinephrine typically causes an increase in blood pressure due to its vasoconstrictive effects. C is incorrect because angioedema is a potential side effect of anaphylaxis and would not be expected to increase after epinephrine administration. D is incorrect because epinephrine helps to improve alertness and consciousness by increasing blood flow to the brain.

Correct Answer: A

Rationale: The correct answer is A because checking a client's blood pressure after administering medication assesses the effectiveness of the intervention. Evaluation involves determining if the desired outcomes were achieved. Administering oxygen therapy (B) is an implementation task. Developing a plan of care (C) is part of the assessment and planning phase. Teaching about dietary options (D) is part of the implementation phase. In conclusion, only option A involves assessing the outcome of an intervention, making it the correct choice for evaluation.

Correct Answer: A

Rationale: The correct answer is A: Inform the physician immediately. This is because finding a lump in the breast could be a sign of breast cancer, and early detection is crucial for effective treatment. The nurse should advise the client to seek medical evaluation promptly for further assessment, such as a mammogram or biopsy. Choice B is incorrect because squeezing the nipple could potentially worsen the condition or spread cancerous cells if present. Choice C is incorrect as waiting until after the next menstrual period may delay necessary medical attention. Choice D is incorrect as using a heating pad could mask symptoms and delay proper diagnosis and treatment.

Correct Answer: A

Rationale: The correct answer is A: Apply zinc oxide to the surrounding skin. This intervention helps create a protective barrier between the irritating drainage or wound compresses and the skin, thus preventing maceration. Zinc oxide has moisture-repelling properties that can help keep the skin dry and reduce the risk of maceration. Choice B (Using a binder) may not address the root cause of maceration and could potentially increase pressure on the wound site. Choice C (Supporting the arm and shoulder with pillows) may provide comfort but does not directly prevent maceration. Choice D (Instructing the client not to shave axillary hair) is unrelated to preventing maceration from irritating drainage or wound compresses.

Correct Answer: B

Rationale: The correct answer is B: Related to impaired balance. The rationale for this is that a client with a cerebellar brain tumor may experience impaired balance due to the cerebellum's role in coordinating voluntary movements and maintaining balance. Impaired balance increases the risk for falls and other injuries. Visual field deficits, difficulty swallowing, and psychomotor seizures are not directly related to the cerebellum's functions in balance and coordination. Therefore, these choices are incorrect for this specific nursing diagnosis.
