Rationale: Lithium is typically administered orally to ensure proper absorption and distribution in the body. It is important to follow the prescribed route of administration to achieve the desired therapeutic effect and avoid potential adverse effects.

Correct Answer: A

Rationale: Antibiotic resistance in bacteria is commonly caused by genes that are carried on plasmids. Plasmids are small, circular DNA molecules that can be transferred between bacteria, allowing for the rapid spread of antibiotic resistance genes throughout bacterial populations. These resistance genes can encode enzymes that inactivate antibiotics, alter antibiotic targets, or even pump antibiotics out of bacterial cells. Plasmid-mediated resistance is a major concern in the healthcare setting as it can lead to the development of multi-drug resistant bacteria, making infections harder to treat. Therefore, the presence and transfer of genes on plasmids play a significant role in the development of antibiotic resistance in bacteria.

Correct Answer: C

Rationale: In the case of a UTI, a sensitivity test is crucial as it identifies the most effective antibiotic to target the specific microorganism causing the infection. This test helps in prescribing the appropriate antibiotic for successful treatment and preventing antibiotic resistance.

Correct Answer: D

Rationale: The correct recommendation for taking calcium carbonate antacid is to drink a glass of water after taking the medication. This practice enhances the effectiveness of the antacid by promoting its dissolution and absorption in the stomach, providing relief from symptoms of heartburn and indigestion.

Correct Answer: C

Rationale: Penicillin is classified as an antibacterial drug, specifically used to treat bacterial infections. It works by inhibiting the growth of bacteria, making it an effective treatment for various bacterial infections.

Correct Answer: A

Rationale: Patient education is a critical component of nursing care, especially for elderly patients who may have difficulty understanding complex medication regimens. A realistic outcome for an 86-year-old patient and their caregiver (daughter) is that they can state the proper way to take the drug. This ensures that the medication is taken correctly, reducing the risk of toxicity or underdosing. While teaching about adverse effects and symptoms of toxicity is important, expecting the patient to recall all symptoms may be unrealistic due to age-related cognitive decline. The most practical and achievable goal is ensuring the patient and caregiver understand the proper administration of the medication.

Correct Answer: A

Rationale: Labetalol should be taken with food to increase absorption and reduce the risk of orthostatic hypotension. Taking it with food helps in better absorption and minimizes the potential drop in blood pressure when standing up, which can occur with this medication.

Correct Answer: D

Rationale: Glargine (Lantus) is classified as a long-acting insulin, providing a slow, steady release of insulin over an extended period, making it suitable for basal insulin requirements. It has a duration of action that can last up to 24 hours, helping to maintain more stable blood sugar levels throughout the day.
