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: B

Rationale: The correct answer is B: Focus on the patient's presenting situation. This is the first step in the problem-oriented approach as it helps the nurse understand the immediate issues and prioritize data collection. By focusing on the presenting situation, the nurse can gather relevant information efficiently. A: Completing questions in chronological order may not address the current problem effectively. C: Making accurate interpretations of the data comes after data collection, not as the first step. D: Conducting an observational overview is important but typically follows focusing on the presenting situation to guide what observations are necessary.

Correct Answer: C

Rationale: The correct answer is C: 1” to 1.5”. When irrigating a colostomy, the client should insert the lubricated catheter about 1” to 1.5” into the stoma. This depth allows for effective irrigation of the colon without causing discomfort or damage. Inserting the catheter too shallow (choice A) may not reach the colon, while inserting it too deep (choices B and D) can cause injury or perforation. Therefore, the optimal depth of 1” to 1.5” ensures proper irrigation while minimizing risks of complications.

Correct Answer: B

Rationale: The correct answer is B: Focus on the patient’s presenting situation. In the problem-oriented approach, the nurse prioritizes the patient's immediate concerns to address them effectively. By focusing on the presenting situation first, the nurse can gather relevant data and identify key issues. This step ensures that the nurse addresses the most pressing problems promptly. A: Completing questions in chronological order may not be necessary and could delay addressing the immediate concern. C: Making accurate interpretations of data should come after gathering relevant information about the presenting situation. D: Conducting an observational overview is important but should come after focusing on the patient's presenting situation to gather specific data.

Correct Answer: A

Rationale: The correct answer is A: Anticipatory grieving. This nursing diagnosis is appropriate because the client's symptoms, such as weight loss, fatigue, and diagnosis of gallbladder cancer, indicate a serious health condition that may lead to emotional distress. Anticipatory grieving involves feelings of loss and sadness related to an anticipated loss, such as the diagnosis of cancer. The client may experience fear, anxiety, and sadness due to the potential impact of the illness on their life. Choice B (Disturbed body image) is incorrect because the client's symptoms are more indicative of a serious health concern rather than body image issues. Choice C (Impaired swallowing) is incorrect as the symptoms described do not suggest difficulty with swallowing. Choice D (Chronic low self-esteem) is also incorrect as the symptoms are more likely related to physical health issues rather than self-esteem concerns.
