Nursing Process Practice Questions

Correct Answer: C

Rationale: The correct answer is C: fluid volume deficit. In diabetes insipidus, there is an excessive amount of dilute urine excreted, leading to dehydration and fluid volume deficit. The posterior pituitary tumor causes a deficiency in antidiuretic hormone (ADH), which regulates water reabsorption in the kidneys. As a result, the client experiences polyuria and polydipsia, leading to fluid volume deficit. Choices A, B, and D are incorrect because diabetes insipidus does not cause fluid volume excess, incontinence, or diarrhea. The key is to recognize the pathophysiology of diabetes insipidus and its impact on fluid balance.

Correct Answer: C

Rationale: The correct answer is C: Implementation. In this step of the nursing process, the nurse is carrying out the care plan based on the identified nursing diagnoses. The nurse is actively providing care and interventions to meet the patient's needs. Assessment (A) is the initial step where data is collected and analyzed. Planning (B) is where goals and interventions are determined based on assessment findings. Evaluation (D) is the final step where the nurse assesses the effectiveness of the care provided. In this scenario, the nurse has already completed the care plan and is now executing the plan by implementing the interventions, making choice C the correct answer.

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: A

Rationale: The correct answer is A: Denial. The client's refusal to accept the diagnosis of diabetes mellitus, stating that no one in their family has had it, indicates denial as a coping mechanism. Denial is a defense mechanism where individuals refuse to acknowledge unpleasant realities. In this case, the client is rejecting the diagnosis to avoid facing the reality of having a chronic condition. The other choices (B: Anger, C: Withdrawal, D: Resolution) do not fit the client's response in this scenario. Anger involves expressing frustration or hostility, withdrawal is avoiding the situation, and resolution is accepting and dealing with the issue.

Correct Answer: D

Rationale: The correct answer is D: �You must avoid hyperextending your neck after surgery.� This is because hyperextending the neck can put excessive strain on the surgical site, leading to potential complications such as bleeding or injury to the incision. Keeping the neck in a neutral position helps promote healing and reduces the risk of complications. A: �The head of your bed must remain flat for 24 hours after surgery.� - Incorrect. Elevating the head of the bed can help reduce swelling and promote drainage after thyroidectomy. B: �You should avoid deep breathing and coughing after surgery.� - Incorrect. Deep breathing and coughing are important to prevent respiratory complications such as pneumonia. C: �You won�t be able to swallow for the first day or two.� - Incorrect. Swallowing may be difficult initially but should improve gradually after surgery.
