Question 1 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 2 of 9

You are the nurse caring for a patient who is to receive IV daunorubicin, a chemotherapeutic agent. You start the infusion and check the insertion site as per protocol. During your most recent check, you note that the IV has infiltrated so you stop the infusion. What is your main concern with this infiltration?

Correct Answer: A

Rationale: The correct answer is A: Extravasation of the medication. Extravasation occurs when the infused medication leaks into surrounding tissues, potentially causing tissue damage and necrosis. This is a serious concern with vesicant medications like daunorubicin. If left untreated, it can lead to severe complications. Choice B: Discomfort to the patient is incorrect because while discomfort may occur with infiltration, the main concern is the potential for tissue damage from extravasation. Choice C: Blanching at the site is incorrect as it is a common sign of infiltration, but the main concern is the possibility of extravasation and tissue damage. Choice D: Hypersensitivity reaction to the medication is incorrect as it is a different type of reaction that is not directly related to infiltration or extravasation.

Question 3 of 9

You are caring for a patient who is being treated on the oncology unit with a diagnosis of lung cancer with bone metastases. During your assessment, you note the patient complains of a new onset of weakness with abdominal pain. Further assessment suggests that the patient likely has a fluid volume deficit. You should recognize that this patient may be experiencing what electrolyte imbalance?

Correct Answer: D

Rationale: The correct answer is D: Hypercalcemia. Bone metastases in lung cancer can lead to increased release of calcium into the blood, causing hypercalcemia. The patient's symptoms of weakness and abdominal pain are consistent with hypercalcemia. Hypernatremia (choice A) is unlikely as the symptoms do not align with high sodium levels. Hypomagnesemia (choice B) and hypophosphatemia (choice C) are less likely as they are not typically associated with bone metastases in lung cancer. In summary, the patient's presentation of weakness and abdominal pain in the setting of lung cancer with bone metastases points to hypercalcemia as the most likely electrolyte imbalance.

Question 4 of 9

A nurse evaluates the following arterial blood gas values in a client: pH 7.48, PaO2 98 mm Hg, PaCO2 28 mm Hg, and HCO3 22 mEq/L. Which client condition should the nurse correlate with these results?

Correct Answer: B

Rationale: The correct answer is B: Anxiety-induced hyperventilation. The arterial blood gas values show a pH of 7.48 (alkalosis) with low PaCO2 (respiratory alkalosis), which is consistent with hyperventilation due to anxiety. HCO3 is within normal range, ruling out metabolic causes. A: Diarrhea and vomiting would lead to metabolic acidosis with low pH and decreased HCO3. C: COPD would typically present with respiratory acidosis (high PaCO2) and normal to high HCO3. D: Diabetic ketoacidosis and emphysema would show metabolic acidosis with low pH and low HCO3.

Question 5 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 6 of 9

. You are caring for a patient who has a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). Your patients plan of care includes assessment of specific gravity every 4 hours. The results of this test will allow the nurse to as

Correct Answer: D

Rationale: The correct answer is D: Fluid volume status. Assessment of specific gravity helps to determine the concentration of solutes in the urine, indicating the degree of hydration or dehydration. In SIADH, there is water retention leading to diluted urine, resulting in low specific gravity. Monitoring specific gravity every 4 hours is crucial in assessing the patient's fluid volume status and response to treatment. A: Nutritional status is not directly assessed by specific gravity. B: Potassium balance is not directly assessed by specific gravity. C: Calcium balance is not directly assessed by specific gravity.

Question 7 of 9

A nurse is planning care for a client who is hyperventilating. The clients arterial blood gas values are pH 7.30, PaO2 94 mm Hg, PaCO2 31 mm Hg, and HCO3 26 mEq/L. Which question should the nurse ask when developing this clients plan of care?

Correct Answer: B

Rationale: The correct answer is B: "You appear anxious. What is causing your distress?" because hyperventilation can be triggered by emotional distress or anxiety. By addressing the underlying cause of the hyperventilation, the nurse can provide appropriate interventions to help the client manage their anxiety and subsequently reduce the hyperventilation episodes. A: "Do you take any over-the-counter medications?" - This question is not directly related to addressing the client's anxiety or distress, which is the primary concern in hyperventilation. C: "Do you have a history of anxiety attacks?" - While relevant to understanding the client's medical history, this question does not address the immediate cause of hyperventilation in this specific situation. D: "You are breathing fast. Is this causing you to feel light-headed?" - This question focuses on the physical symptoms of hyperventilation rather than exploring the emotional or psychological triggers, which are essential in managing hyperventilation caused by anxiety.

Question 8 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 9 of 9

A nurse assesses a client who was started on intraperitoneal therapy 5 days ago. The client reports abdominal pain and feeling warm. For which complication of this therapy should the nurse assess this client?

Correct Answer: D

Rationale: The correct answer is D, infection. The client's symptoms of abdominal pain and feeling warm are indicative of a potential infection, which is a common complication of intraperitoneal therapy. Step-by-step rationale: 1. Abdominal pain can be a sign of peritonitis, an infection of the peritoneal cavity. 2. Feeling warm may indicate a fever, a common symptom of infection. 3. Prompt assessment and treatment of infection are crucial to prevent complications. Summary of other choices: A, allergic reaction - unlikely given the symptoms described; B, bowel obstruction - does not align with the symptoms provided; C, catheter lumen occlusion - not typically associated with abdominal pain and feeling warm.
