Question 1 of 5
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 2 of 5
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 3 of 5
You are working on a burns unit, and one of your acutely ill patients is exhibiting signs and symptoms of third spacing. Based on this change in status, you should expect the patient to exhibit signs and symptoms of what imbalance?
Correct Answer: D
Rationale: Rationale: Third spacing occurs when fluid shifts from the intravascular space to interstitial spaces, leading to hypovolemia. This results in decreased circulating blood volume, leading to signs of hypovolemia such as tachycardia, hypotension, and low urine output. Metabolic alkalosis, hypermagnesemia, and hypercalcemia are not directly related to third spacing and are not the expected imbalances in this scenario.
Question 4 of 5
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 5 of 5
You are an emergency-room nurse caring for a trauma patient. Your patient has the following arterial blood gas results: pH 7.26, PaCO2 28, HCO3 11 mEq/L. How would you interpret these results?
Correct Answer: D
Rationale: To interpret the given ABG results: 1. pH <7.35 indicates acidosis. 2. PaCO2 <35 indicates respiratory alkalosis. 3. HCO3 <22 indicates metabolic acidosis. Therefore, the ABG results show metabolic acidosis (low pH, low HCO3) with compensatory respiratory alkalosis (low PaCO2). This means the body is trying to compensate for the metabolic acidosis by decreasing PaCO2 through hyperventilation. Option D is correct. Options A, B, and C are incorrect as they do not align with the ABG results and the principles of acid-base balance.
