PN ATI Capstone Proctored Comprehensive Assessment B Quizlet

Correct Answer: D

Rationale: The trough level of vancomycin should be drawn just before the next dose is administered, typically about 30 minutes before the scheduled dose. Since the morning dose is at 0700, the trough level should be drawn at 1800. This timing ensures an accurate measurement of the lowest concentration of the drug in the client's system before the next dose is given. Choice A (2100) is too close to the next dose, choice B (900) is too early, and choice C (1300) is also too far from the next dose.

Correct Answer: A

Rationale: Administering oxygen is the priority intervention for a client with a pulmonary embolism. Pulmonary embolism can lead to impaired gas exchange, causing hypoxemia. Administering oxygen helps to maintain adequate oxygenation levels. Thoracentesis is not indicated for a pulmonary embolism, as it is a procedure to remove fluid or air from the pleural space, not a treatment for embolism. Elevating the client's lower extremities is not a priority in the management of a pulmonary embolism. Administering anticoagulant therapy is important in the treatment of pulmonary embolism to prevent further clot formation, but it is not the first intervention. Oxygen administration takes precedence to address the immediate oxygenation needs of the client.

Correct Answer: A

Rationale: The correct answer is A. Tying wrist restraints to the bed rails is a safety hazard because if the bed rails are lowered, the restraints can tighten and cause injury or asphyxiation. Choice B, placing a bedside table across the foot of the bed, may not be ideal for convenience but does not pose a direct safety hazard. Choice C, leaving a meal tray at the bedside from breakfast, is more of an infection control issue than an immediate safety hazard. Choice D, having a call light extension cord pinned to the bedspread, is also not a direct safety hazard unless it poses a risk of entanglement or tripping, which is not indicated in the scenario.

Correct Answer: A

Rationale: The correct answer is A. Troponin I is a specific marker for myocardial infarction, and levels of 8 ng/mL are elevated, indicating heart muscle damage. Brain natriuretic peptide (BNP) is more related to heart failure rather than myocardial infarction, making choice B incorrect. Alanine aminotransferase (ALT) is a liver enzyme and not specific to myocardial infarction, so choice C is incorrect. High-density lipoprotein (HDL) is a type of cholesterol and is not typically used to diagnose or monitor myocardial infarction, making choice D incorrect.

Correct Answer: D

Rationale: The correct answer is D. Elbow splints are utilized to prevent the child from touching the surgical site. However, it is essential to remove them periodically to conduct range-of-motion exercises to prevent joint stiffness. Choices A, B, and C are incorrect because providing an orthodontic pacifier, offering fluids using a straw, and cleansing the suture line with a cotton-tip swab are not directly related to postoperative care following a cleft palate repair.
