Which of the following diuretics inhibits sodium reabsorption in the kidneys while saving K+ and Hydrogen ions?

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.

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.

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.

Correct Answer: A

Rationale: Barbiturates are central nervous system depressants that can exacerbate conditions such as emphysema, hypertension, and acute intermittent porphyria.

Correct Answer: A

Rationale: A decoction is a liquid preparation made by boiling vegetable substances with water. This process helps extract the beneficial properties and compounds from the plant material into the liquid. Decoctions are commonly used in herbal medicine to prepare medicinal remedies by simmering roots, bark, or other plant parts in water for a period of time.
