The nurse in the mental health unit observes a client hitting the wall repeatedly with the hands after an upsetting family therapy session. The nurse should recognize that the client is exhibiting which of the following defense mechanisms?
- A. projection
- B. displacement
- C. rationalization
- D. reaction formation
Correct Answer: B
Rationale: Defense mechanisms are unconscious mental processes used to protect individuals from uncomfortable thoughts, internal conflicts, and external stresses. Defense mechanisms may be therapeutic to clients with anxiety. However, with excessive use, defense mechanisms may become notherapeutic because they involve a degree of self-deception and reality distortion that can result in poor interpersonal relationships, irrational behavior, and decreased productivity.

The nurse approaches a 4-year-old boy to administer a medication. The child has no identification armband. Which action is most appropriate?
- A. Check the room and bed number the child is in with the room and bed number on the medication order and administer the medication if they agree
- B. Ask the child what his name is before administering the medication
- C. Ask the child if his name is George (the name on the medication order) and administer the medication if the child says that is his name
- D. Ask the adults at the bedside what the child's name is and administer the medication if the adults verify the name of the child
Correct Answer: D
Rationale: Verifying the child's identity with adults at the bedside ensures safety, as children may not reliably confirm their own identity, and room/bed numbers are not sufficient for identification.
The nurse working in an extended care facility transcribes a prescription from the health care provider for a single daily dose of 150 mg of ranitidine; this is to be taken orally at bedtime for treatment of gastroesophageal reflux disease. Of the following prescriptions, which one is transcribed correctly?
- A. Ranitidine 150 mg daily by mouth
- B. Ranitidine 150 mg per os qhs
- C. Ranitidine 150 mg po qd nightly
- D. Ranitidine 150 mg PO at bedtime

An 80-year-old woman has been hospitalized for three days with pneumonia. She is now able to sit in a chair for the first time. How should the nurse plan care for today?

- C. Give her a bed bath and come back later to get her up in the chair. Make the bed while she is up in the chair.
- D. Give her a bed bath and immediately get her up in the chair so the bed can be made.
Correct Answer: C
Rationale: A bed bath conserves energy, and later chair transfer allows bed-making, optimizing rest and mobility for a recovering pneumonia patient.

- A. To lower the blood alcohol level
- B. To prevent gross tremors
- C. To prevent Wernicke encephalopathy
- D. To treat seizures related to acute alcohol withdrawal
Correct Answer: C
Rationale: Thiamine prevents Wernicke encephalopathy, a neurological disorder from thiamine deficiency common in chronic alcoholism. It does not lower alcohol levels, prevent tremors, or treat seizures directly.
