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 nurse is caring for a client who is receiving an epidural infusion for pain management. Which assessment finding requires immediate intervention from the nurse?

Correct Answer: B

Rationale: The correct answer is B: Report of headache and stiff neck. This finding indicates a potential complication of epidural anesthesia called a post-dural puncture headache, which can lead to serious consequences like meningitis or subdural hematoma. The nurse should act immediately by notifying the healthcare provider for further evaluation and management. Redness at the catheter insertion site (A) may indicate local inflammation but doesn't require immediate intervention. Temperature elevation (C) could be a sign of infection but isn't as urgent as a headache and stiff neck. Pain rating of 8 (D) is important but doesn't indicate an immediate threat to the client's health like a post-dural puncture headache.

Question 3 of 9

A nurse is caring for a client who is having a subclavian central venous catheter inserted. The client begins to report chest pain and difficulty breathing. After administering oxygen, which action should the nurse take next?

Correct Answer: B

Rationale: The correct answer is B: Prepare to assist with chest tube insertion. Chest pain and difficulty breathing after subclavian central venous catheter insertion could indicate a pneumothorax, a potential complication. Chest tube insertion is indicated to help re-expand the lung and relieve the pressure in the thoracic cavity. This intervention takes priority over the other options because it addresses the potential life-threatening complication of a pneumothorax. Administering nitroglycerin (choice A) is not indicated for chest pain in this scenario. Placing a sterile dressing over the IV site (choice C) is not appropriate for managing chest pain and difficulty breathing. Re-positioning the client into the Trendelenburg position (choice D) is not effective in addressing a pneumothorax and may worsen the client's condition.

Question 4 of 9

The nurse is providing care for a patient with chronic obstructive pulmonary disease. When describing the process of respiration the nurse explains how oxygen and carbon dioxide are exchanged between the pulmonary capillaries and the alveoli. The nurse is describing what process?

Correct Answer: A

Rationale: The correct answer is A: Diffusion. In respiration, oxygen and carbon dioxide are exchanged between the alveoli and pulmonary capillaries through the process of diffusion. Here's the rationale: 1. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. 2. In the alveoli, oxygen moves from the air (higher concentration) into the blood (lower concentration) and carbon dioxide moves from the blood (higher concentration) into the air (lower concentration). 3. This exchange occurs passively, without the need for energy input, which is characteristic of diffusion. Summary of other choices: B: Osmosis involves the movement of water across a semi-permeable membrane, not gas exchange. C: Active transport requires energy input to move molecules against their concentration gradient, not seen in gas exchange. D: Filtration involves the movement of molecules through a membrane under pressure, not the passive movement of gases in respiration.

Question 5 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 6 of 9

A nurse teaches a client who is being discharged home with a peripherally inserted central catheter (PICC). Which statement should the nurse include in this clients teaching?

Correct Answer: A

Rationale: The correct answer is A: "Avoid carrying your grandchild with the arm that has the central catheter." This is important because carrying a child can put strain on the arm where the catheter is inserted, increasing the risk of dislodging or damaging the catheter. It is crucial to protect the integrity of the catheter site to prevent complications such as infection or bleeding. Choice B is incorrect because placing the arm with the central catheter in a sling during the day is unnecessary and could restrict the client's mobility and lead to discomfort. Choice C is incorrect because flushing the PICC line with normal saline should be done by a healthcare professional and not the client themselves. Choice D is incorrect because using the arm with the central catheter for most activities of daily living can increase the risk of accidental dislodgment or damage to the catheter. It is important to be cautious and limit certain activities to protect the catheter and maintain its function.

Question 7 of 9

A nurse is caring for a client who has the following arterial blood values: pH 7.12, PaO2 56 mm Hg, PaCO2 65 mm Hg, and HCO3 22 mEq/L. Which clinical situation should the nurse correlate with these values?

Correct Answer: A

Rationale: The correct answer is A: Diabetic ketoacidosis in a person with emphysema. The arterial blood values show a low pH (acidosis), high PaCO2 (respiratory acidosis), and normal HCO3 (compensatory metabolic alkalosis). This pattern is consistent with a mixed acid-base disorder seen in diabetic ketoacidosis where metabolic acidosis from ketone production is partially compensated by respiratory acidosis from decreased alveolar ventilation due to emphysema. The other choices do not align with the given blood values. Choice B is incorrect as it would typically show respiratory alkalosis. Choice C would show respiratory alkalosis with low PaCO2. Choice D would result in metabolic acidosis with low HCO3.

Question 8 of 9

The physician has ordered a peripheral IV to be inserted before the patient goes for computed tomography. What should the nurse do when selecting a site on the hand or arm for insertion of an IV catheter?

Correct Answer: B

Rationale: The correct answer is B because considering potential effects on the patient's mobility is crucial when selecting a site for IV insertion. Mobility can be affected if the IV is placed in a joint area or on the dominant hand. This could limit the patient's ability to move freely during and after the procedure. Therefore, it is important to choose a site that will not hinder the patient's movement. A: Choosing a hairless site is not the most important factor when selecting a site for IV insertion. C: Having the patient hold his arm over his head before insertion is not necessary and may cause discomfort for the patient. D: Leaving the tourniquet on for at least 3 minutes is not recommended as it can lead to complications such as venous stasis.

Question 9 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.
