1.A nurse prepares to insert a peripheral venous catheter in an older adult client. Which action should the nurse take to protect the clients skin during this procedure?

Correct Answer: D

Rationale: The correct answer is D: Place a washcloth between the skin and tourniquet. This step helps protect the client's skin by providing a barrier between the tourniquet and the skin, reducing the risk of skin irritation or damage. Lowering the extremity below the heart (A) can increase venous pressure and make it harder to insert the catheter. Warm compresses (B) can dilate blood vessels and increase the risk of bruising. Tapping the skin lightly (C) can irritate the skin and is unnecessary for skin protection.

Question 2 of 9

A client with a serum potassium of 7.5 mEq/L and cardiovascular changes needs immediate intervention. Which prescription should the nurse implement first?

Correct Answer: C

Rationale: The correct answer is C. The client's high serum potassium level of 7.5 mEq/L can lead to serious cardiovascular complications like arrhythmias. The immediate priority is to lower potassium levels rapidly to prevent cardiac arrest. Administering dextrose 20% and regular insulin IV push helps shift potassium from extracellular to intracellular space, lowering serum levels quickly. Option A (Kayexalate) is not as rapid as insulin therapy. Option B (low-potassium diet) is not immediate. Option D (hemodialysis) is effective but not as quick as insulin therapy for urgent potassium reduction.

Question 3 of 9

. A nurse assesses a client who had an intraosseous catheter placed in the left leg. Which assessment finding is of greatest concern?

Correct Answer: D

Rationale: The correct answer is D. A cool lower extremity can indicate impaired circulation due to the intraosseous catheter placement, leading to compartment syndrome or tissue necrosis. This finding requires immediate intervention to prevent serious complications. Choices A, B, and C are incorrect because the duration of catheter placement, poor vascular access, and the specific location of the catheter do not directly impact circulation and tissue perfusion as significantly as a cool lower extremity.

Question 4 of 9

A nurse is caring for a client who is experiencing excessive diarrhea. The clients arterial blood gas values are pH 7.28, PaO2 98 mm Hg, PaCO2 45 mm Hg, and HCO3 16 mEq/L. Which provider order should the nurse expect to receive?

Correct Answer: B

Rationale: The correct answer is B: Sodium bicarbonate 100 mEq diluted in 1 L of D5W. In this case, the client is experiencing metabolic acidosis due to low HCO3 levels (16 mEq/L) with a low pH (7.28). Sodium bicarbonate helps correct metabolic acidosis by increasing the HCO3 levels. Furosemide (A) is a diuretic and can worsen the client's electrolyte imbalance. Mechanical ventilation (C) is not indicated for metabolic acidosis. Indwelling urinary catheter (D) does not address the underlying acid-base imbalance. Therefore, the nurse should expect the provider to order sodium bicarbonate to correct the metabolic acidosis.

Question 5 of 9

While assessing a clients peripheral IV site, the nurse observes a streak of red along the vein path and palpates a 4-cm venous cord. How should the nurse document this finding?

Correct Answer: A

Rationale: The correct answer is A: Grade 3 phlebitis at IV site. This finding indicates inflammation of the vein due to irritants from the IV catheter, supported by red streak and palpable cord. Grade 3 phlebitis involves pain, redness, swelling, and palpable venous cord. Infection (B) typically presents with signs like pus, warmth, and fever. Thrombosis (C) involves a blood clot, not a palpable cord. Infiltration (D) is leakage of IV fluid into surrounding tissues, not related to palpable cord and red streak.

Question 6 of 9

A nurse is caring for a client who is experiencing moderate metabolic alkalosis. Which action should the nurse take?

Correct Answer: D

Rationale: The correct answer is D: Teach the client fall prevention measures. In metabolic alkalosis, the client may experience muscle weakness and confusion, increasing the risk of falls. Teaching fall prevention measures is essential to ensure the client's safety. Monitoring hemoglobin and hematocrit values (A) is not directly related to managing metabolic alkalosis. Administering furosemide (B) is not appropriate for metabolic alkalosis. Encouraging deep breaths (C) may not address the underlying cause of the alkalosis.

Question 7 of 9

You are doing discharge teaching with a patient who has hypophosphatemia during his time in hospital. The patient has a diet ordered that is high in phosphate. What foods would you teach this patient to include in his diet? Select all that do not apply

Correct Answer: B

Rationale: The correct answer is B: Beef. While beef is a good source of protein, it is not high in phosphate. Milk, poultry, and liver are high in phosphate and would be beneficial for a patient with hypophosphatemia. Beef is not typically a significant source of phosphate and therefore would not be as effective in increasing phosphate levels in the body compared to the other options. It is important for the patient to focus on consuming foods that are high in phosphate to help correct the hypophosphatemia.

Question 8 of 9

You are caring for a patient with a diagnosis of pancreatitis. The patient was admitted from a homeless shelter and is a vague historian. The patient appears malnourished and on day 3 of the patients admission total parenteral nutrition (TPN) has been started. Why would you know to start the infusion of TPN slowly?

Correct Answer: B

Rationale: The correct answer is B: Malnourished patients receiving parenteral nutrition are at risk for hypophosphatemia if calories are started too aggressively. Patient with pancreatitis may have depleted levels of phosphorus due to malnutrition, and rapid initiation of TPN can further decrease phosphorus levels, leading to hypophosphatemia. This can result in respiratory failure, muscle weakness, and arrhythmias. Choice A is incorrect because patients receiving TPN are not specifically at risk for hypercalcemia due to rapid initiation of calories. Choice C is incorrect because rapid fluid infusion can lead to hypernatremia, not related to TPN initiation. Choice D is incorrect because the rationale provided for slow initiation is not related to digestive enzymes but rather to prevent hypophosphatemia in malnourished patients.

Question 9 of 9

The community health nurse is performing a home visit to an 84-year-old woman recovering from hip surgery. The nurse notes that the woman seems uncharacteristically confused and has dry mucous membranes. When asked about her fluid intake, the patient states, I stop drinking water early in the day because it is just too difficult to get up during the night to go to the bathroom. What would be the nurses best response?

Correct Answer: B

Rationale: The correct answer is B because limiting fluids can lead to dehydration, which can cause confusion and dry mucous membranes. Adjusting the timing of fluids can help maintain hydration without causing frequent nighttime bathroom trips. Choice A is incorrect because hospital readmission is not necessary at this point. Choice C is incorrect as it normalizes confusion post-surgery and dangerous practice of avoiding urination at night. Choice D is incorrect because urine accumulation in the bladder does not directly cause confusion; dehydration is the primary concern.
