Correct Answer: C
Rationale: When administering Penicillin, one of the adverse effects to watch out for as a sign of an acute allergic reaction is the development of a skin rash or hives. This reaction may indicate an allergic response to the medication. It is important for the nurse to monitor the patient closely for any signs of an allergic reaction, including skin changes, and to act promptly if such symptoms arise. An acute allergic reaction can progress to a severe life-threatening condition known as anaphylaxis, so prompt recognition and intervention are critical in such cases.
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.
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.
A patient is in the emergency department with new-onset atrial fibrillation. Which order for digoxin would most likely have the fastest therapeutic effect?
- A. Digoxin 0.25 mg PO daily
- B. Digoxin 1 mg PO now; then 0.25 mg PO daily
- C. Digoxin 0.5 mg IV push daily
- D. Digoxin 1 mg IV push now; then 0.25 mg IV daily
Correct Answer: D
Rationale: When a patient requires immediate treatment for atrial fibrillation with digoxin, the fastest way to achieve a therapeutic effect is through intravenous administration. Option D, Digoxin 1 mg IV push now; then 0.25 mg IV daily, is the most appropriate order in this scenario. Intravenous administration allows for rapid absorption and onset of action, making it the preferred route for urgent situations like atrial fibrillation. By giving an initial loading dose intravenously, followed by a lower maintenance dose IV daily or orally, the patient can quickly achieve therapeutic digoxin levels to help stabilize the heart rhythm. Option D provides the most rapid and effective way to manage new-onset atrial fibrillation with digoxin.
