Question 1

A patient with major depressive disorder refuses to get out of bed and states 'What is the point?' Which nursing diagnosis is the priority?

Accepted Answer

Risk for self-directed violence related to hopelessness

Answer

Hopelessness is a significant risk factor for suicidal ideation. 'What is the point?' may indicate passive suicidal ideation. Safety assessment and risk for self-directed violence are the priority nursing concerns before addressing mobility or other issues.

Question 2

What is the therapeutic serum level of lithium for maintenance therapy?

Accepted Answer

0.6–1.2 mEq/L

Answer

Therapeutic lithium levels for maintenance are 0.6–1.2 mEq/L. During acute mania, levels of 0.8–1.2 mEq/L are targeted. Toxicity begins around 1.5 mEq/L and is life-threatening above 2.0 mEq/L. Signs of toxicity include tremor, ataxia, nausea, and confusion.

Question 3

Which finding suggests neuroleptic malignant syndrome (NMS) in a patient taking antipsychotics?

Accepted Answer

High fever, muscle rigidity, altered consciousness, and autonomic instability

Answer

NMS is a rare, potentially fatal reaction to antipsychotics characterized by the tetrad: hyperthermia (often >40°C), severe muscle rigidity ('lead-pipe' rigidity), altered consciousness, and autonomic instability (diaphoresis, tachycardia, BP fluctuations). Immediate discontinuation and supportive treatment are required.

Question 4

What type of therapy is most evidence-based for PTSD?

Accepted Answer

Trauma-focused cognitive behavioral therapy (TF-CBT) and EMDR

Answer

Trauma-focused CBT and Eye Movement Desensitization and Reprocessing (EMDR) have the strongest evidence base for PTSD treatment. They help patients process traumatic memories, modify negative thought patterns, and reduce hyperarousal and avoidance behaviors.

Question 5

A patient with anorexia nervosa is admitted with a weight of 35 kg at 165 cm height (BMI 12.9). What is the immediate priority?

Accepted Answer

Medical stabilization: electrolyte management and nutritional rehabilitation

Answer

Severe anorexia (BMI <15) is a medical emergency. Life-threatening complications include cardiac arrhythmias (from hypokalemia and hypomagnesemia), refeeding syndrome, and multi-organ failure. Medical stabilization, electrolyte monitoring, and controlled nutritional rehabilitation precede psychological interventions.
