Nursing Elites

1. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?

• A. To reduce abdominal pressure on the diaphragm
• B. To promote retraction of the intercostal accessory muscles of respiration
• C. To promote bronchodilation and effective airway clearance
• D. To decrease pressure on the medullary center which stimulates breathing

Correct answer: A

Rationale: Elevating the head of the bed to 30 degrees is done to reduce abdominal pressure on the diaphragm, aiding in lung expansion and oxygenation. This position helps improve respiratory mechanics by allowing the diaphragm to move more effectively. Choice B is incorrect as elevating the head of the bed does not directly promote retraction of the intercostal accessory muscles of respiration. Choice C is incorrect because although elevating the head of the bed can assist with airway clearance, its primary purpose in ARDS is to decrease pressure on the diaphragm. Choice D is incorrect because reducing pressure on the medullary center is not the main goal of elevating the head of the bed; the focus is on enhancing lung function and oxygen exchange.

2. A client with acute renal failure (ARF) is admitted for uncontrolled type 1 diabetes mellitus and hyperkalemia. The nurse administers an IV dose of regular insulin per sliding scale. Which intervention is the most important for the nurse to include in this client’s plan of care?

• A. Monitor the client’s cardiac activity via telemetry.
• B. Maintain venous access with an infusion of normal saline.
• C. Assess glucose levels via finger stick every 4 to 6 hours.
• D. Evaluate hourly urine output for the return of normal renal function.

Correct answer: A

Rationale: Monitoring cardiac activity is crucial in this scenario because hyperkalemia can lead to serious cardiac dysrhythmias, which can be life-threatening. Regular monitoring of the client’s cardiac activity via telemetry allows for early detection of any potential cardiac complications. Maintaining venous access with a normal saline infusion is important for hydration but does not address the immediate risk of cardiac dysrhythmias posed by hyperkalemia. Assessing glucose levels is essential in diabetes management but is not the priority when dealing with hyperkalemia-induced cardiac risks. Evaluating hourly urine output for the return of normal renal function is important in ARF but is not as urgent as monitoring the client's cardiac activity in the context of hyperkalemia.

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

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

Correct answer: C

Rationale: The correct answer is C because a significant difference in calf circumference between the legs is a classic sign of DVT. This is due to the obstruction of blood flow in the deep veins of the leg, leading to swelling in the affected limb. Choices A, B, and D are not typical findings of DVT. Choice A describes a neurological response, choice B indicates a bruise on the right calf, and choice D describes pitting edema in both lower extremities, which are not specific signs of DVT.

4. The nurse is preparing to administer an IM injection to a 6-month-old child. Which injection site is best for the nurse to use?

• A. Vastus lateralis
• B. Deltoid
• C. Ventrogluteal
• D. Dorsogluteal

Correct answer: A

Rationale: The vastus lateralis is the preferred site for IM injections in infants due to their limited muscle mass and safety. Infants do not have well-developed muscle mass, making the vastus lateralis the best option for IM injections. The deltoid muscle is typically used for older children and adults. Ventrogluteal and dorsogluteal sites are not recommended for infants due to safety concerns, including the risk of damaging the sciatic nerve. Therefore, the correct choice is the vastus lateralis for IM injections in infants.

5. What instruction should the nurse provide a pregnant client experiencing heartburn?

• A. Limit fluid intake between meals to prevent stomach over-distension
• B. Take an antacid at bedtime and when symptoms worsen
• C. Maintain an upright position for two hours after eating
• D. Eat small meals throughout the day to avoid a full stomach

Correct answer: D

Rationale: The correct answer is D: 'Eat small meals throughout the day to avoid a full stomach.' Heartburn is common in pregnancy due to increased intra-abdominal pressure and hormonal changes. Consuming small, frequent meals prevents the stomach from becoming overly full, reducing the likelihood of acid reflux and heartburn. Choice A is incorrect because limiting fluid intake between meals may not significantly impact heartburn. Choice B is not ideal as antacids should be taken as directed by a healthcare provider, not just at bedtime or when symptoms worsen. Choice C is less effective advice, as maintaining an upright position after eating may not directly address the root cause of heartburn.
