Which of the following does not describe intravenous injection.

Correct Answer: D

Rationale: The statement "Convenient, safe, economical" does not accurately describe intravenous injection. Intravenous injection is generally considered to be less convenient compared to other routes of administration due to the need for proper training, sterile technique, and close monitoring during drug administration. While it can be effective in delivering drugs quickly and directly into the bloodstream, it is not always the safest or most economical option. Intravenous administration carries risks such as infection, phlebitis, and possible adverse reactions that need to be carefully monitored. Additionally, the cost of intravenous drug administration tends to be higher due to the need for specialized equipment and trained personnel.

Correct Answer: A

Rationale: Orthostatic hypotension is a common side effect seen in ACE Inhibitors, Beta Blockers, and Calcium Channel Blockers.

Correct Answer: A

Rationale: Carbamazepine can cause leukopenia, including neutropenia, as a side effect. A neutrophil count of 1,200/mm3 is below the normal range and indicates a potential adverse effect. Platelet count, uric acid, and SGPT levels are within normal ranges and do not indicate side effects. Therefore, the neutrophil count is the concerning result.

Correct Answer: C

Rationale: The correct nursing intervention when administering Nitroglycerine to a patient like Samuel is to remove the transdermal patch 10-12 hours every night to prevent tolerance. Tolerance can develop rapidly with Nitroglycerine, leading to decreased effectiveness in managing anginal attacks. By removing the patch at night, the body has a chance to "reset" and reduce the likelihood of tolerance development. This practice helps maintain the drug's effectiveness and ensures better symptom control for the patient.

Correct Answer: D

Rationale: Pain relief in pregnancy avoids fetal harm. Ketorolac , an NSAID, risks ductal closure, disrupting fetal circulation. Acetaminophen , Codeine , Hydrocodone , and Morphine (E) are safer. Ketorolac's prostaglandin inhibition contraindicates it late in gestation.
