Nursing Elites

1. A male client admitted three days ago with respiratory failure is intubated, and 40% oxygen per facemask is initiated. Currently, his temperature is 99°F, capillary refill is less than 4 seconds, and respiratory effort is within normal limits. What outcome should the nurse evaluate to measure for successful extubation?

• A. Exhibits adequate tissue perfusion
• B. Remains free of injury
• C. Remains free of infection
• D. Maintains effective breathing pattern

Correct answer: D

Rationale: Successful extubation relies on the patient's ability to maintain an effective breathing pattern. This indicates that the patient can adequately oxygenate and ventilate without the need for mechanical support. Monitoring tissue perfusion, preventing infection, and ensuring safety are important but not directly related to the immediate criteria for successful extubation. Tissue perfusion, injury prevention, and infection control are crucial aspects of overall patient care but are not the primary factors to consider when evaluating readiness for extubation.

2. Which assessment finding is most indicative of deep vein thrombosis (DVT) in a client's right leg?

• A. Dorsiflexes the right foot and left on command
• B. A 3 by 5 cm ecchymosis area covering the right calf
• C. Right calf is 3 cm larger in circumference than the left
• D. Bilateral lower extremity has 3+ pitting edema

Correct answer: C

Rationale: The correct answer is C because a significant increase in the circumference of the right calf compared to the left calf is a classic sign of deep vein thrombosis (DVT). Option A is incorrect as dorsiflexing the right foot and left on command does not specifically indicate DVT. Option B describes an ecchymosis area which is more indicative of a bruise rather than DVT. Option D suggests bilateral lower extremity edema, which is not specific to DVT and can be seen in various conditions such as heart failure or renal issues.

3. One hour after delivery, the nurse is unable to palpate the uterine fundus of a client and notes a large amount of lochia on the perineal pad. Which intervention should the nurse implement first?

• A. Empty the bladder using an indwelling urinary catheter
• B. Increase the rate of the IV containing oxytocin (Pitocin)
• C. Assess for shock by determining the blood pressure
• D. Perform gentle massage at the level of the umbilicus

Correct answer: D

Rationale: Gentle massage at the level of the umbilicus is the initial intervention to help contract the uterus and reduce bleeding, which is crucial in managing postpartum hemorrhage. Emptying the bladder can help with fundal displacement, but massage should be done first to stimulate uterine contractions. Increasing the IV oxytocin rate is a possible intervention but not the initial priority. Assessing for shock is important, but addressing the uterine atony through massage takes precedence to prevent further hemorrhage.

4. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

5. Which action should the nurse include in the plan of care for a client who is receiving acyclovir (Zovirax) IV for the treatment of herpes zoster (shingles)?

• A. Initiate cardiac telemetry monitoring
• B. Maintain continuous pulse oximetry
• C. Perform capillary glucose measurements
• D. Monitor serum creatinine levels

Correct answer: D

Rationale: The correct answer is to monitor serum creatinine levels. Acyclovir can potentially impact kidney function, making it essential to monitor serum creatinine levels to assess renal function. Option A, initiating cardiac telemetry monitoring, is not directly related to acyclovir administration for herpes zoster. Option B, maintaining continuous pulse oximetry, is more relevant in assessing respiratory status rather than monitoring for acyclovir-related side effects. Option C, performing capillary glucose measurements, is not directly associated with acyclovir therapy for herpes zoster.
