Question 1 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 2 of 9

A home care nurse prepares to administer intravenous medication to a client. The nurse assesses the site and reviews the clients chart prior to administering the medication: Client: Thomas Jackson DOB: 5/3/1936 Gender: Male January 23 (Today): Right uppe

Correct Answer: B

Rationale: The correct answer is B: Administer the prescribed medication. The nurse has assessed the client's site and reviewed the chart, indicating readiness to administer the medication. It is crucial to follow the healthcare provider's order and administer the prescribed medication as planned. Notifying the provider (A) is unnecessary if all assessments are normal. Discontinuing the PICC line (C) without a valid reason can lead to complications. Switching to oral route (D) should only be considered if there are specific contraindications for the intravenous route. It's important to prioritize safe and effective medication administration based on the client's condition and healthcare provider's orders.

Question 3 of 9

After teaching a client who was malnourished and is being discharged, a nurse assesses the clients understanding. Which statement indicates the client correctly understood teaching to decrease risk for the development of metabolic acidosis?

Correct Answer: A

Rationale: The correct answer is A: "I will drink at least three glasses of milk each day." Milk is a good source of calcium and bicarbonate, which can help buffer excess acids in the body and prevent metabolic acidosis. Calcium also plays a role in maintaining the acid-base balance. Option B is incorrect because while eating well-balanced meals is important for overall health, it does not specifically address the prevention of metabolic acidosis. Option C is irrelevant to the prevention of metabolic acidosis. Option D is incorrect because avoiding salting food does not directly address the underlying issue of metabolic acidosis related to malnutrition.

Question 4 of 9

A nurse evaluates a clients arterial blood gas values (ABGs): pH 7.30, PaO2 86 mm Hg, PaCO2 55 mm Hg, and HCO3 22 mEq/L. Which intervention should the nurse implement first?

Correct Answer: A

Rationale: The correct answer is A: Assess the airway. The nurse should prioritize airway assessment as the client's ABGs indicate respiratory acidosis (low pH, high PaCO2). This suggests potential airway obstruction or inadequate ventilation. Ensuring a patent airway is crucial for adequate oxygenation. Administering bronchodilators (B) or mucolytics (D) may help with airway clearance but should come after ensuring a clear airway. Providing oxygen (C) is important, but addressing the underlying respiratory acidosis by first assessing the airway is the priority in this situation to prevent further deterioration.

Question 5 of 9

A nurse assesses a client who is experiencing an acid-base imbalance. The clients arterial blood gas values are pH 7.34, PaO2 88 mm Hg, PaCO2 38 mm Hg, and HCO3 19 mEq/L. Which assessment should the nurse perform first?

Correct Answer: A

Rationale: The correct answer is A: Cardiac rate and rhythm. In an acid-base imbalance, the pH is below the normal range indicating acidosis. The nurse should assess the cardiac rate and rhythm first because acidosis can have negative effects on the cardiovascular system. Acidosis can lead to arrhythmias and decreased cardiac output. Monitoring the cardiac rate and rhythm is crucial to detect any cardiac complications early. Choices B, C, and D are not the priority in this situation as they are not directly impacted by acid-base imbalances.

Question 6 of 9

You are called to your patients room by a family member who voices concern about the patients status. On assessment, you find the patient tachypnic, lethargic, weak, and exhibiting a diminished cognitive ability. You also find 3+ pitting edema. What electrolyte imbalance is the most plausible cause of this patients signs and symptoms?

Correct Answer: C

Rationale: The correct answer is C: Hyperchloremia. In this scenario, the patient's symptoms point towards fluid overload, which can lead to hyperchloremia due to excessive chloride intake. 3+ pitting edema suggests fluid retention, a common symptom of hyperchloremia. Additionally, tachypnea can occur as a compensatory mechanism for metabolic acidosis seen in hyperchloremia. Lethargy, weakness, and diminished cognitive ability can be attributed to electrolyte imbalances impacting nerve and muscle function. Choice A: Hypocalcemia is less likely as it typically presents with neuromuscular irritability, not lethargy. Choice B: Hyponatremia usually presents with neurological symptoms like confusion and seizures, not the symptoms described. Choice D: Hypophosphatemia typically presents with muscle weakness, not the full constellation of symptoms described.

Question 7 of 9

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 8 of 9

A nurse is caring for a client who has the following laboratory results: potassium 3.4 mEq/L, magnesium 1.8 mEq/L, calcium 8.5 mEq/L, sodium 144 mEq/L. Which assessment should the nurse complete first?

Correct Answer: D

Rationale: The correct answer is D: Read food labels to determine sodium content. The nurse should assess the client's sodium level of 144 mEq/L, which is slightly above the normal range. High sodium intake can lead to fluid retention, hypertension, and other health issues. By reading food labels to determine sodium content, the nurse can identify sources of high sodium intake in the client's diet and provide appropriate dietary recommendations. This assessment is crucial in managing the client's sodium levels and overall health. Assessing the client's dietary intake of foods high in potassium (Choice A) is not the priority in this case since the client's potassium level is within the normal range. Assessing the client's neuromuscular status (Choice B) is important but not the first priority when considering the electrolyte imbalances present. Assessing the client's fluid intake and output (Choice C) is also important but does not address the immediate concern related to the client's elevated sodium level.

Question 9 of 9

A medical-surgical nurse is concerned about the incidence of complications related to IV therapy, including bloodstream infection. Which intervention should the nurse suggest to the management team to make the biggest impact on decreasing complications

Correct Answer: A

Rationale: The correct answer is A: Initiate a dedicated team to insert access devices. This intervention is the most effective in decreasing complications related to IV therapy because having a dedicated team specialized in inserting access devices ensures that the procedure is done correctly each time, reducing the risk of complications such as bloodstream infections. Choice B is not as effective because additional education for all nurses may not guarantee consistent skill levels in IV insertion. Choice C may limit access but does not address the root cause of complications. Choice D focuses on skin preparation, which is important but not as impactful as having a specialized team for IV insertion.
