Extract:
Question 1 of 5
Inability to leave one's home because of avoidance of severe anxiety suggests the existence of which anxiety disorder?
Correct Answer: B
Rationale: Agoraphobia is characterized by a fear of situations where escape might be difficult or help unavailable leading to avoidance behavior such as being unable to leave home. It often co-occurs with panic disorder. Other disorders do not specifically involve this avoidance behavior.
Question 2 of 5
A patient diagnosed with bipolar disorder is prescribed lithium carbonate. Which laboratory result should prompt the nurse to hold the medication and notify the healthcare provider?
Correct Answer: D
Rationale: An elevated creatinine level (2.1 mg/dL) indicates possible renal dysfunction which is a concern for lithium use. Lithium is excreted by the kidneys and impaired renal function increases the risk of lithium toxicity. Normal potassium slightly low sodium and normal calcium do not warrant withholding the medication.
Question 3 of 5
Which patient is at the highest risk of developing postpartum depression?
Correct Answer: C
Rationale: A history of depression and minimal social support are significant risk factors for postpartum depression. Previous mental health issues increase the likelihood of postpartum mood disorders and lack of support makes coping more difficult. A healthy pregnancy supportive partner or no family history of mental illness reduce the risk but do not eliminate it entirely.
Question 4 of 5
A 25-year-old patient with generalized anxiety disorder presents to the ED with shortness of breath,dizziness,and tingling in the fingers. The nurse reviews the ABG results: pH: 7.50 PaCO2: 30 mmHg HCO3: 24 mEq/L. What is the most likely acid-base imbalance?
Correct Answer: C
Rationale: Respiratory alkalosis is indicated by a pH of 7.50 (alkalosis) and a PaCO2 of 30 mmHg which is lower than the normal range (35-45 mmHg). This low PaCO2 suggests that the patient is hyperventilating likely due to anxiety which causes the body to excrete too much CO2. Other options do not match the lab results.

Correct Answer: B
Rationale: Anxiety often leads to physical symptoms such as urinary frequency due to increased sympathetic nervous system activity. Chills are not typical rapid speech is more common in severe anxiety and distorted perceptual fields are seen in panic or severe anxiety not moderate anxiety.
