Question 1 of 9

You are making initial shift assessments on your patients. While assessing one patients peripheral IV site, you note edema around the insertion site. How should you document this complication related to IV therapy?

Correct Answer: C

Rationale: Correct Answer: C - Infiltration Rationale: 1. Infiltration occurs when IV fluid leaks into surrounding tissues, causing edema. 2. Documenting infiltration is important for appropriate management. 3. Air emboli, phlebitis, and fluid overload are unrelated to edema around IV site. Summary of Incorrect Choices: A. Air emboli: This is a serious condition caused by air entering the bloodstream, not related to edema. B. Phlebitis: Inflammation of the vein, usually presenting with redness and pain, not edema. D. Fluid overload: Excess fluid volume in the body, leading to symptoms like shortness of breath, not edema.

Question 2 of 9

A nurse is caring for a client who has a serum calcium level of 14 mg/dL. Which provider order should the nurse implement first?

Correct Answer: A

Rationale: The correct answer is A: Encourage oral fluid intake. When a client has hypercalcemia (serum calcium level of 14 mg/dL), the priority is to increase fluid intake to promote renal calcium excretion. This helps prevent complications such as renal calculi. The first step is to dilute the serum calcium by increasing fluid intake, which can help lower the serum calcium level. Connecting the client to a cardiac monitor (B) is not the priority as hypercalcemia affects the kidneys more than the heart. Assessing urinary output (C) is important but encouraging fluid intake is more immediate. Administering oral calcitonin (Calcimar) (D) is not the first action as it is a medication used for long-term management of hypercalcemia, not the immediate priority.

Question 3 of 9

A nurse assesses a client who is prescribed furosemide (Lasix) for hypertension. For which acid-base imbalance should the nurse assess to prevent complications of this therapy?

Correct Answer: D

Rationale: The correct answer is D: Metabolic alkalosis. Furosemide, a loop diuretic, can lead to potassium depletion and metabolic alkalosis due to excessive loss of chloride and hydrogen ions. The nurse should assess for signs of metabolic alkalosis such as confusion, muscle weakness, and dysrhythmias to prevent complications. Respiratory acidosis and alkalosis are not directly related to furosemide therapy. Metabolic acidosis is less likely due to furosemide's mechanism of action.

Question 4 of 9

You are caring for a patient admitted with a diagnosis of acute kidney injury. When you review your patients most recent laboratory reports, you note that the patients magnesium levels are high. You should prioritize assessment for which of the followin

Correct Answer: A

Rationale: Step 1: High magnesium levels can lead to hypermagnesemia, which can cause decreased neuromuscular function. Step 2: Diminished deep tendon reflexes are a sign of neuromuscular impairment, indicating potential hypermagnesemia. Step 3: Assessing for diminished deep tendon reflexes is crucial to monitor neuromuscular function in patients with high magnesium levels. Summary: A is correct because hypermagnesemia affects neuromuscular function. B, C, and D are incorrect as they do not directly relate to the effects of high magnesium levels.

Question 5 of 9

. A 73-year-old man comes into the emergency department (ED) by ambulance after slipping on a small carpet in his home. The patient fell on his hip with a resultant fracture. He is alert and oriented; his pupils are equal and reactive to light and accommodation. His heart rate is elevated, he is anxious and thirsty, a Foley catheter is placed, and 40 mL of urine is present. What is the nurses most likely explanation for the low urine output?

Correct Answer: D

Rationale: The correct answer is D. The man's elevated heart rate, anxiety, and low urine output indicate a sympathetic reaction. This reaction stimulates the renin-angiotensin-aldosterone system, leading to decreased urine output. The sympathetic response triggers the release of renin, which activates angiotensin II and aldosterone, causing vasoconstriction and water reabsorption in the kidneys, ultimately reducing urine output. Choice A is incorrect because low urine output is not solely due to urinating before arrival. Choice B is incorrect as there is no indication of traumatic brain injury or ADH deficiency. Choice C is incorrect as atrial natriuretic peptide in heart failure typically increases urine output.

Question 6 of 9

The nurse is caring for a patient in metabolic alkalosis. The patient has an NG tube to low intermittent suction for a diagnosis of bowel obstruction. What drug would the nurse expect to find on the medication orders?

Correct Answer: A

Rationale: The correct answer is A: Cimetidine. In metabolic alkalosis, the blood pH is elevated due to excess bicarbonate. Cimetidine is a histamine-2 receptor antagonist that can help decrease gastric acid production, which can contribute to alkalosis. Maalox (B) is an antacid used to treat acid-related conditions, not alkalosis. Potassium chloride elixir (C) is used to correct potassium imbalances, not directly related to alkalosis. Furosemide (D) is a loop diuretic used to treat fluid retention and edema, not specifically indicated for metabolic alkalosis.

Question 7 of 9

A nurse assesses a client who is admitted for treatment of fluid overload. Which manifestations should the nurse expect to find? (Select all that do not apply.)

Correct Answer: C

Rationale: Step 1: Fluid overload leads to increased fluid volume in the body, causing skin to appear pale, cool, and clammy due to poor circulation. Step 2: "Warm and pink skin" is not a typical manifestation of fluid overload. Step 3: Therefore, the correct answer is C. Summary: A: Increased pulse rate - Possible in fluid overload due to increased volume causing increased workload on the heart. B: Distended neck veins - Common in fluid overload due to increased venous pressure. C: Warm and pink skin - Incorrect, as skin is usually pale, cool, and clammy. D: Skeletal muscle weakness - Not directly related to fluid overload.

Question 8 of 9

A patient with a longstanding diagnosis of generalized anxiety disorder presents to the emergency room. The triage nurse notes upon assessment that the patient is hyperventilating. The triage nurse is aware that hyperventilation is the most common cause

Correct Answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation leads to excessive elimination of carbon dioxide, causing a decrease in PaCO2 levels, resulting in respiratory alkalosis. This is the most common cause of hyperventilation. Respiratory acidosis (choice A) occurs when there is retention of carbon dioxide. Increased PaCO2 (choice C) is a consequence of respiratory acidosis, not alkalosis. CNS disturbances (choice D) can lead to abnormal breathing patterns but are not the most common cause of hyperventilation.

Question 9 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.
