Nursing Process Practice Questions

Correct Answer: A

Rationale: The correct answer is A: It inhibits deoxyribonucleic acid (DNA) synthesis. Mitomycin works by cross-linking DNA, leading to inhibition of DNA synthesis and ultimately causing cell death. This mechanism of action makes it effective against rapidly dividing cancer cells. B: It�s cell cycle-phase specific - This is incorrect because mitomycin is not specific to a particular phase of the cell cycle. C: It inhibits ribonucleic acid (RNA) synthesis - This is incorrect as mitomycin primarily targets DNA synthesis, not RNA synthesis. D: It inhibits protein synthesis - This is incorrect as mitomycin's main mechanism of action is through DNA cross-linking, not protein synthesis inhibition.

Correct Answer: D

Rationale: Rationale: Acetylcysteine (Mucomyst) is the antidote for acetaminophen overdose. It works by replenishing glutathione, which helps neutralize the toxic metabolite of acetaminophen. Pentostatin, Fludarabine, and Auranofin are not antidotes for acetaminophen overdose and are used for different conditions. Acetylcysteine is the correct choice as it directly counteracts the toxic effects of acetaminophen.

Correct Answer: A

Rationale: The correct answer is A: A clot can enter the circulation. When a clotted cannula is aggressively flushed, the force can dislodge the clot, allowing it to enter the circulation and potentially leading to serious complications such as embolism. Incorrect choices: B: An air embolism can enter the circulation - In the context of a clotted cannula, air embolism is less likely compared to a clot entering the circulation. C: A painful arterial spasm can occur - Arterial spasm is a potential complication but not directly related to flushing a clotted cannula. D: Fluid extravasation into surrounding tissue can occur - Flushing a clotted cannula may not specifically lead to fluid extravasation, as it is more related to needle dislodgement or improper placement.

Correct Answer: A

Rationale: The correct answer is A because providing clear liquids only until the patient can swallow solid foods is not a recommended nursing intervention to prevent aspiration. Clear liquids do not require the same level of swallowing coordination as solid foods, so it may not help improve swallowing ability. B: Having the patient swallow twice after each bite can help clear the throat and reduce the risk of aspiration. C: Placing food on the unaffected side of the mouth can help direct the food towards the stronger side for swallowing. D: Checking the patient's mouth for pocketing of food is important to ensure that food is not being retained in the mouth, which could lead to aspiration.

Correct Answer: A

Rationale: Correct Answer: A - Cerebral edema Rationale: 1. SIADH leads to water retention and dilutional hyponatremia. 2. Diuretic therapy aims to increase urine output and correct fluid imbalance. 3. If the client does not comply, excessive water retention can lead to cerebral edema. 4. Cerebral edema is a serious complication that can cause neurological deficits. Summary: - B: Severe hyperkalemia is unlikely as diuretics would help excrete excess potassium. - C: Hypovolemic shock is not expected as fluid restriction may prevent rapid volume loss. - D: Tetany is not a direct consequence of non-compliance with treatment for SIADH.
