A patient is scheduled to receive chemotherapy drugs that will cause myelosuppression. Which action by the nurse will be most important?
- A. Monitor for a change in temperature.
- B. Evaluate gastrointestinal function.
- C. Assess for evidence of cardiac compromise.
- D. Question the patient about changes in sense of taste.
Correct Answer: A
Rationale: Myelosuppression, a common side effect of chemotherapy, leads to a decrease in white blood cells, red blood cells, and platelets. A drop in white blood cells, particularly neutrophils, increases the risk of infection. Monitoring for a change in temperature is critical because fever is often the first sign of infection in neutropenic patients. Early detection allows for prompt intervention, such as administering antibiotics, to prevent life-threatening complications. While gastrointestinal function, cardiac compromise, and changes in taste are important to assess, they are not as immediately life-threatening as an undetected infection in a myelosuppressed patient.

The nurse is administering Penicillin to a patient who has tested positive for strep throat. The nurse knows to look for which of the following adverse e昀昀ects as a sign of an acute allergic reaction?
- A. blurred vision
- B. tinnitus
- C. skin rash/hives
- D. vomiting
Correct Answer: C
Rationale: An acute allergic reaction to Penicillin can present with symptoms such as skin rash or hives. This is a common sign of an allergic reaction and can indicate the patient is having an adverse response to the medication. It is essential for the nurse to monitor the patient closely for any signs of allergic reactions, including hives, as they can quickly progress to more severe reactions such as anaphylaxis. Other adverse effects listed in the choices, such as blurred vision, tinnitus, and vomiting, are not typically associated with an acute allergic reaction to Penicillin.
Which of the following diuretics inhibits sodium reabsorption in the kidneys while saving K+ and Hydrogen ions?
- A. Spironolactone
- B. Furosemide
- C. Hydrochlorothiazide
- D. Bumetanide
Correct Answer: A
Rationale: Spironolactone is a potassium-sparing diuretic, which means it inhibits sodium reabsorption in the kidneys, while saving potassium and hydrogen ions. It accomplishes this by acting as an aldosterone antagonist, blocking the action of aldosterone. Aldosterone is a hormone that normally promotes sodium reabsorption in the kidneys and leads to potassium and hydrogen ion excretion. By inhibiting aldosterone, spironolactone promotes sodium excretion while conserving potassium and hydrogen ions.
What should you monitor when given a patient Clopidogrel?
- A. Signs of thrombotic thrombolytic purpura
- B. Bleeding during therapy
- C. CBC with differential and platelet count
- D. All the above
Correct Answer: D
Rationale: When monitoring a patient on Clopidogrel therapy, it is important to monitor for signs of thrombotic thrombolytic purpura (TTP), bleeding during therapy, and changes in blood counts. Clopidogrel is an antiplatelet medication that works by preventing platelets from sticking together and forming clots. Monitoring for signs of TTP is necessary as clopidogrel has been associated with an increased risk of TTP in some patients. Additionally, monitoring for bleeding is crucial as clopidogrel, like other antiplatelet medications, can increase the risk of bleeding complications. Monitoring a complete blood count (CBC) with differential and platelet count allows healthcare providers to assess the patient's blood cell levels and ensure that the medication is not causing any adverse effects on blood counts. Therefore, monitoring all of the above parameters is essential to ensure the safety and efficacy of clopidogrel therapy.
Basis for pharmacotherapeutics
- A. Selective action of drugs with regard to diagnosis, preventive and treatment of disease
- B. Bioavailability of drugs
- C. Biologic half-life of drugs
- D. Renal clearance and elimination of drugs
Correct Answer: A
Rationale: The basis for pharmacotherapeutics lies in the selective action of drugs with regard to the diagnosis, prevention, and treatment of diseases. Pharmacotherapeutics involves the use of drugs to manage diseases and improve health outcomes. Drugs are carefully selected based on their mechanism of action, efficacy, safety profile, and suitability for a specific condition. The goal is to achieve optimal therapeutic effects while minimizing potential adverse effects. By understanding the selective action of drugs in targeting specific pathways or processes in the body, healthcare providers can customize treatment regimens to individual patients and achieve the best possible outcomes.
What nursing interventions should you do when a patient is on Albuterol (select all that apply)
- A. Assess lung sounds , Pulse , and Blood pressure before administering
- B. Monitor for changes in behavior
- C. Observe for paradoxical bronchospasms
- D. Assess for abdominal distention
Correct Answer: A
Rationale: A. Assess lung sounds, Pulse, and Blood pressure before administering: It is important to assess the patient's baseline lung sounds, pulse rate, and blood pressure before administering Albuterol to monitor for any changes that may occur after administration. This is crucial in determining the effectiveness of the medication and detecting any potential side effects.
