1. Which of the following assessments is the most important for a patient receiving IV potassium?
- A. Respiratory rate
- B. Heart rate
- C. Blood pressure
- D. Oxygen saturation
Correct answer: C
Rationale: The most important assessment for a patient receiving IV potassium is monitoring blood pressure. IV potassium can cause significant changes in cardiac function, leading to adverse effects such as arrhythmias and cardiac arrest. While respiratory rate, heart rate, and oxygen saturation are important parameters to monitor in clinical practice, blood pressure takes precedence in patients receiving IV potassium due to its direct impact on cardiovascular function. Changes in blood pressure can be an early indicator of potassium-induced cardiac complications, making it crucial to monitor closely during administration.
2. Alteplase recombinant, or tissue plasminogen activator (t-PA), a thrombolytic enzyme, is administered during the first 6 hours after onset of myocardial infarction (MI) to:
- A. Control chest pain.
- B. Reduce coronary artery vasospasm.
- C. Control the arrhythmias associated with MI.
- D. Revascularize the blocked coronary artery.
Correct answer: D
Rationale: Alteplase recombinant, or t-PA, is a thrombolytic enzyme used to dissolve clots and revascularize the blocked coronary artery in patients experiencing a myocardial infarction (MI). Administering t-PA within the first 6 hours of MI onset is crucial to restore blood flow to the affected area and minimize cardiac tissue damage. Therefore, the correct answer is to revascularize the blocked coronary artery. Choices A, B, and C are incorrect because while controlling chest pain, reducing coronary artery vasospasm, and managing arrhythmias are important goals in managing MI, the primary purpose of administering t-PA within the first 6 hours is to restore blood flow by dissolving clots and revascularizing the blocked coronary artery.
3. When working with a large population of African-American clients at a community health center, which priority assessment should a nurse include?
- A. Measure height and weight.
- B. Assess blood pressure.
- C. Observe for any signs of abuse.
- D. Ask about medications.
Correct answer: B
Rationale: Assessing blood pressure is the priority assessment when working with a population of African-American clients due to the high prevalence of hypertension in this group. African Americans have a higher risk of hypertension, which can lead to complications like end-stage renal disease. Monitoring blood pressure allows for the early detection and management of hypertension. While measuring height and weight, observing for signs of abuse, and asking about medications are important assessments, assessing blood pressure is crucial in this context to address the specific health needs of African-American clients.
4. What is an expected outcome when a client is receiving an IV administration of furosemide?
- A. Increased blood pressure.
- B. Increased urine output.
- C. Decreased pain.
- D. Decreased premature ventricular contractions.
Correct answer: B
Rationale: The correct answer is B: Increased urine output. Furosemide is a loop diuretic that works by inhibiting the reabsorption of sodium and chloride in the ascending loop of Henle in the kidneys, leading to increased urine production. This diuretic effect helps to reduce fluid volume in the body, making it an expected outcome when a client is receiving furosemide. Choice A, increased blood pressure, is incorrect because furosemide typically causes a decrease in blood pressure due to its diuretic effect. Choice C, decreased pain, and choice D, decreased premature ventricular contractions, are unrelated to the pharmacological action of furosemide.
5. A client who underwent preadmission testing 1 week before surgery had blood drawn for several serum laboratory studies. Which abnormal laboratory results should the nurse report to the surgeon’s office? Select all that apply.
- A. Hematocrit 30%
- B. Sodium 141 mEq/L
- C. Hemoglobin 8.9 g/dL
- D. Platelets 210,000 cells/mm3
Correct answer: C
Rationale: The correct answer is C. Hemoglobin level of 8.9 g/dL is below the normal range, indicating anemia. Anemia can affect the body's ability to carry oxygen, impacting surgical outcomes. Hematocrit level is an indirect measure of red blood cells, which also reveals anemia when low. Sodium level of 141 mEq/L and platelet count of 210,000 cells/mm3 are within normal ranges and do not require immediate reporting. Abnormal sodium levels can lead to various issues, but in this scenario, it is not a concern for surgical readiness. Platelet count is vital for blood clotting, and a count of 210,000 cells/mm3 is considered normal, so it does not need urgent attention.
