Correct Answer: C

Rationale: In the early stages of hypovolemic shock, the body initiates compensatory mechanisms to maintain perfusion. One of these mechanisms is an increased respiratory rate to improve oxygen delivery. This helps to offset the decreased circulating blood volume. A heart rate of 60/min (choice A) is not expected in hypovolemic shock; instead, tachycardia is a common finding due to the body's attempt to maintain cardiac output. Increased urinary output (choice B) is not typically seen in hypovolemic shock as the body tries to conserve fluid. Hypothermia (choice D) is usually a late sign of shock when the body's compensatory mechanisms are failing, and perfusion is severely compromised.

Correct Answer: B

Rationale: The correct first action for a client with an NG tube experiencing nausea and decreased gastric secretions is to irrigate the NG tube with sterile water. This helps alleviate blockages and can improve the client's symptoms. Increasing the suction pressure (Choice A) may exacerbate the issue and cause further discomfort. Turning the client onto their left side (Choice C) is not directly related to addressing the reported symptoms. Replacing the NG tube with a new one (Choice D) should be considered only after attempting initial interventions like irrigation.

Correct Answer: C

Rationale: The correct answer is C: Decreased bowel sounds. In hypokalemia, decreased bowel sounds are common due to slowed peristalsis. Hyperactive reflexes (choice A) and increased deep tendon reflexes (choice D) are more indicative of hyperkalemia. A strong, bounding pulse (choice B) is not typically associated with hypokalemia.

Correct Answer: A

Rationale: The correct answer is A: Clean the wound and apply a hydrocolloid dressing. This step is crucial in managing a pressure ulcer as it helps protect the ulcer from infection and promotes healing by creating a moist environment conducive to tissue repair. Choice B, debriding necrotic tissue and applying antibiotics, is more suitable for managing infected pressure ulcers but not as the initial step. Choice C, applying an alginate dressing and elevating the affected area, may be part of the management but is not the initial step. Choice D, using moisture-retentive dressings and repositioning frequently, is important for prevention but not the first step in managing an existing pressure ulcer.

Correct Answer: B

Rationale: The correct answer is to suction the tracheostomy first. When a client with a tracheostomy is experiencing increased secretions and labored breathing, suctioning the tracheostomy is the priority intervention to clear the airway and improve breathing. Administering a bronchodilator (Choice A) may help with breathing but should come after ensuring the airway is clear. Encouraging the client to cough (Choice C) may not be effective in clearing secretions from the tracheostomy. Notifying the provider (Choice D) can be done after ensuring immediate airway clearance.
