Question 1 of 5
A patient is mowing his lawn on a hot Saturday afternoon. He begins to notice chest pain. What should his first action be?
Correct Answer: B
Rationale: The patient's first action should be to stop mowing and sit or lie down. Chest pain can be a symptom of a heart attack, and it is important for the patient to immediately rest and avoid physical strain. Continuing to mow the lawn could worsen the condition or lead to further complications. Sitting or lying down will help reduce the heart's workload and minimize the exertion on the body. If the chest pain continues or worsens, seeking medical help should be the next course of action.
Question 2 of 5
The nurse is preparing to give a potassium supplement. Which laboratory test should be checked before the patient receives a dose of potassium?
Correct Answer: B
Rationale: Before administering a potassium supplement to a patient, it is crucial to check the patient's serum potassium level. This is because if the serum potassium level is already elevated or within the high end of the normal range, giving additional potassium could lead to hyperkalemia, which can be life-threatening. Conversely, if the serum potassium level is low (hypokalemia), then administering potassium supplementation may be necessary to correct the deficiency. Monitoring the serum potassium level helps ensure safe and effective treatment with potassium supplements. It is a critical part of assessing the patient's electrolyte balance and overall health status.
Question 3 of 5
What action is often recommended to help reduce tolerance to transdermal nitroglycerin therapy?
Correct Answer: A
Rationale: Omitting a dose of transdermal nitroglycerin therapy once a week is often recommended to help reduce tolerance. Tolerance to nitroglycerin can develop with continuous use, limiting its effectiveness. By omitting a dose once a week, you are essentially giving the body a break from the medication and preventing tolerance from developing. This strategy can help maintain the efficacy of the nitroglycerin therapy over time. It is important to follow the guidance of a healthcare provider when making any changes to the dosing regimen of nitroglycerin to ensure safety and effectiveness.
Question 4 of 5
The nurse is preparing to transfuse a patient with a unit of packed red blood cells (PRBCs). Which intravenous solution is correct for use with the PRBC transfusion?
Correct Answer: B
Rationale: 0.9% sodium chloride (NS), also known as normal saline, is the correct intravenous solution to use with packed red blood cell (PRBC) transfusion. NS is isotonic and compatible with blood products, making it the preferred solution for blood transfusions to prevent hemolysis of red blood cells. Other solutions such as D5W, D5NS, and D5LR are not recommended for use with PRBC transfusions due to their potential to cause hemolysis or affect the stability of the blood product.
Question 5 of 5
Samuel, a 65-year-old patient comes into the hospital for an anginal attack. Which of the following is an important nursing intervention when administering Nitroglycerine?
Correct Answer: C
Rationale: The correct nursing intervention when administering Nitroglycerine to a patient like Samuel is to remove the transdermal patch 10-12 hours every night to prevent tolerance. Tolerance can develop rapidly with Nitroglycerine, leading to decreased effectiveness in managing anginal attacks. By removing the patch at night, the body has a chance to "reset" and reduce the likelihood of tolerance development. This practice helps maintain the drug's effectiveness and ensures better symptom control for the patient.
