A patient who is severely anemic also has acute heart failure with severe edema due to fluid

Correct Answer: D

Rationale: In a patient who is severely anemic, the primary goal is to raise the hemoglobin and hematocrit levels. Packed red blood cells (PRBCs) contain a concentrated dose of red blood cells and are given to increase oxygen-carrying capacity in cases of significant anemia. Fresh frozen plasma, albumin, and whole blood do not specifically address the issue of low hemoglobin levels, making them less appropriate choices for this scenario.

Correct Answer: C

Rationale: When administering a Serotonin Antagonist, it is important to monitor the patient's respiratory rate. Serotonin antagonists can have side effects that impact the respiratory system, such as respiratory depression. Monitoring the patient's respiratory rate can help identify any signs of respiratory distress or compromise early on, allowing for prompt intervention and prevention of any serious complications. It is crucial to closely monitor the patient's breathing when administering medications that can potentially affect the respiratory system to ensure patient safety.

Correct Answer: A

Rationale: Insulin glargine is a type of long-acting insulin that is given via subcutaneous injection. Subcutaneous administration involves injecting the medication into the fatty tissue layer just beneath the skin. This route allows for slow and consistent absorption of the insulin into the bloodstream, providing a prolonged effect on lowering blood sugar levels. Insulin cannot be taken orally because it would be broken down by the digestive system before it could be effective. Intravenous (IV) administration is also not appropriate for insulin glargine because it is meant to have a slow, sustained release in the body, which cannot be achieved with IV administration. Sublingual administration, where a medication is placed under the tongue for absorption, is not suitable for insulin as it requires specific pathways for absorption that are not present under the tongue.

Correct Answer: C

Rationale: Penicillin is classified as an antibiotic drug, specifically an antibacterial agent. It is used to treat various bacterial infections by inhibiting the growth of bacteria or killing them directly. Therefore, it is not categorized as an antiarrhythmic, anticonvulsant, or mood stabilizer. Instead, Penicillin falls under the classification of drugs that are effective against bacterial infections, making it an "anti-ineffective" drug.

Correct Answer: A

Rationale: ACE (Angiotensin-Converting Enzyme) inhibitors are known to act on the Renin-Angiotensin-Aldosterone System (RAAS) by blocking the conversion of angiotensin I to the active angiotensin II. Angiotensin II is a potent vasoconstrictor and also stimulates the release of aldosterone, leading to increased blood pressure. By inhibiting ACE, ACE inhibitors help to lower blood pressure and reduce the secretion of aldosterone, thereby decreasing the overall vasoconstriction and volume expansion effects of the RAAS. Examples of ACE inhibitors include medications such as lisinopril, enalapril, and captopril.
