Correct Answer: D

Rationale: The lowest priority patient care task in this scenario is addressing the emotional need of the patient who is crying because his daughter did not visit him today. While emotional support is important, the other needs - providing water, assisting to the bathroom, and addressing chest pain - are physical needs that must take priority as they directly impact the patient's well-being and health. It is crucial to acknowledge and address emotional needs but in this situation, the physical needs of the patients should be addressed first.

Correct Answer: C

Rationale: Radiating pain is the correct term for pain that originates in one part of the body and extends to other related areas. In this scenario, the pain starting in the shoulder and traveling down the arm describes radiating pain. Referred pain (Choice A) is pain felt at a site different from the actual origin of the pain. Superficial pain (Choice B) is pain that arises from the skin or tissues just beneath it. Precipitating pain (Choice D) refers to pain that is triggered by specific actions or events, not the characteristic described in the question.

Correct Answer: D

Rationale: Substance P is a neurotransmitter found in the brain and the dorsal horn of the spinal column, not just in the brain. It is associated with pain transmission and modulation. Substance P is known to cause inflammation, edema, and pain. While it plays a role in pain perception, it does not decrease a client's sensitivity to pain (Choice A), nor are its levels typically drawn before administering narcotic analgesics (Choice B). Although substance P is involved in pain control, it is not responsible for managing depression (Choice C). Therefore, the correct statement is that substance P is found in the dorsal horn of the spinal column.

Correct Answer: D

Rationale: The correct answer is D. Clients with chronic obstructive pulmonary disease have difficulty exhaling fully due to the weak alveolar walls from the disease process. Pursed-lip breathing helps prevent alveolar collapse by maintaining positive pressure in the airways during exhalation. This is the major reason for using pursed-lip breathing in individuals with chronic obstructive lung disease. Choices A, B, and C are incorrect because they do not directly address the main purpose of pursed-lip breathing, which is to prevent alveolar collapse and improve exhalation in these patients.

Correct Answer: A

Rationale: Urinary hesitancy occurs when a client has difficulty starting a flow of urine while using the bathroom. Hesitancy may be due to physiological factors, such as obstruction from an enlarged prostate, or due to psychological factors, such as anxiety or embarrassment. Oliguria refers to decreased urine output, retention is the inability to empty the bladder fully, and urgency is the sudden and strong need to urinate.
