Correct Answer: B

Rationale: The initial step in providing healthcare for a patient is to determine the needs of the patient. This step involves assessing the patient's condition, listening to their concerns, and understanding what care or treatment they require. Obtaining and interpreting vital signs (Choice A) is a crucial step but typically follows the assessment of the patient's needs. Developing a plan of care (Choice C) and obtaining lab work and x-rays (Choice D) come after understanding the patient's needs and assessing their condition.

Correct Answer: D

Rationale: The correct answer is D. A beta blocker should be withheld if the apical pulse is below 60, as it can further decrease the heart rate. Choice A is not a reason to question administering the medication as the blood pressure is within a normal range for a client with essential hypertension. Choice B is not directly related to the administration of a beta blocker. Choice C suggests a potential side effect of an ACE inhibitor, not a beta blocker.

Correct Answer: C

Rationale: The Ambulance Squad is the module composed of four medical specialists and two vehicles. This squad is responsible for providing medical care during transportation. Choices A, B, and D are incorrect as they do not match the description provided in the question. The Patient Holding Squad focuses on a different aspect of patient care, the Surgical Squad is more specialized in surgical procedures, and the Area Support Squad provides a different type of support.

Correct Answer: A

Rationale: The correct answer is A: Stomach irritation and bleeding. Nonsteroidal anti-inflammatory drugs (NSAIDs) can lead to stomach irritation and bleeding by affecting the gastric mucosa. Stomatitis and esophagitis (choice B) are not commonly associated with NSAIDs. Impaired folate absorption (choice C) is not a typical side effect of NSAIDs. Increased potassium excretion (choice D) is not a common side effect of NSAIDs.

Correct Answer: C

Rationale: Patients with a history of peptic ulcer disease should avoid nonsteroidal anti-inflammatory drugs (NSAIDs) because they can worsen peptic ulcers. NSAIDs inhibit the production of prostaglandins, which help protect the stomach lining. Acetaminophen (Choice A) is a safer alternative for pain relief in patients with peptic ulcers. Antacids (Choice B) can actually help in symptom relief by neutralizing stomach acid. Antihistamines (Choice D) are not known to worsen peptic ulcers and are generally safe for use in patients with this condition.
