Correct Answer: A

Rationale: When a client in active labor has ruptured membranes, the priority action for the nurse is to apply a fetal heart rate monitor. This is crucial for continuous monitoring of the baby's heart rate and ensuring fetal well-being. Initiating fundal massage may be indicated for uterine atony after delivery, not for ruptured membranes during labor. Administering oxytocin IV could be appropriate in some cases to augment labor, but it is not the immediate priority after ruptured membranes. Inserting an indwelling urinary catheter is not necessary solely based on ruptured membranes; it may be indicated for specific situations like epidural anesthesia where the client cannot void.

Correct Answer: C

Rationale: The correct action for the nurse to take is to check the client's creatinine level before administering vancomycin. Vancomycin is known to be nephrotoxic, so assessing the client's renal function before administering the medication is crucial to prevent further kidney damage. Administering the medication over 15 minutes (Choice A) is not the priority in this scenario as renal function assessment takes precedence. Monitoring urine output (Choice B) is important for assessing renal function but checking creatinine level directly provides more accurate information. Assessing for allergies to antibiotics (Choice D) is also important but not as essential as checking the creatinine level due to the nephrotoxic nature of vancomycin.

Correct Answer: C

Rationale: Using a mechanical lift is an appropriate ergonomic technique as it reduces the risk of injury to both the nurse and the client by promoting safe client handling practices. Choice A is incorrect as standing with feet shoulder-width apart provides better balance and stability during lifting. Choice B is incorrect as raising the client's knees is not directly related to ergonomic principles. Choice D is incorrect as placing a gait belt around the client's waist is a safety measure but does not specifically demonstrate an understanding of ergonomic principles.

Correct Answer: A

Rationale: The correct answer is A: Encourage the client to take frequent rest periods. During acute mania, individuals often experience high levels of energy, decreased need for sleep, and increased activity levels. Encouraging the client to take frequent rest periods can help prevent exhaustion and promote better self-regulation. Choice B is incorrect because withdrawing TV privileges may not be directly related to managing acute mania. Choice C is incorrect as placing the client in seclusion can exacerbate feelings of anxiety and agitation. Choice D is incorrect as spending time in the day room may not address the need for rest and relaxation that is crucial during acute mania.

Correct Answer: B

Rationale: The correct answer is B. A blood pressure of 110/70 mm Hg is a finding that the nurse should report to the provider when caring for a client with heart failure receiving digoxin. Digoxin can cause hypotension, so a low blood pressure reading should be reported promptly to the provider for further evaluation and management. Choices A, C, and D are within normal ranges and would not require immediate reporting. A heart rate of 60/min is considered normal, but any further decrease should be monitored. A serum potassium level of 4 mEq/L is also within the normal range. A blood pressure of 120/80 mm Hg is typically considered normal as well.
