A nurse is preparing to administer haloperidol 4 mg IM to a client who has schizophrenia. Available is haloperidol injection 5 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.8"]
Calculation:
- Identify the ordered dose and available concentration
Ordered Dose: 4 mg
Available Concentration: 5 mg/mL
- Calculate the volume to administer
Volume to administer = Ordered Dose ÷ Concentration
Volume to administer = 4 ÷ 5
Volume to administer = 0.8 mL

Correct Answer is A
Explanation
A. Suppression: Suppression is a conscious, intentional exclusion of distressing thoughts or feelings from awareness. The client is choosing to postpone thinking about their cancer diagnosis until after their son’s wedding, which reflects adaptive use of suppression to temporarily manage anxiety.
B. Projection: Projection involves attributing one’s own unacceptable thoughts or feelings onto another person. The client is not blaming or transferring feelings onto someone else, so projection is not demonstrated in this statement.
C. Splitting: Splitting is the inability to integrate positive and negative qualities of self or others, often seen in borderline personality disorder. The client’s statement does not reflect this distortion or black-and-white thinking.
D. Reaction formation: Reaction formation occurs when an individual behaves in a way opposite to their unacceptable feelings or impulses. The client is not exhibiting opposite behavior to hide true feelings; they are consciously postponing attention to stressors, which aligns with suppression.
Correct Answer is ["A","B","C","E"]
Explanation
A. Diaphoresis: Sweating is a common manifestation of opioid and stimulant withdrawal. The client’s recent heroin and methamphetamine use puts them at risk for autonomic hyperactivity, including diaphoresis.
B. Anxiety: Anxiety is a frequent symptom during withdrawal from both opioids and stimulants. The client’s agitation and fear of worsening withdrawal indicate heightened risk for emotional and psychological distress.
C. Insomnia: Sleep disturbances, including difficulty falling or staying asleep, are common during withdrawal from substances such as heroin and methamphetamine. Insomnia contributes to fatigue and irritability during the withdrawal period.
D. Slurred speech: Slurred speech is more indicative of acute intoxication, central nervous system depressant effects, or neurological impairment rather than withdrawal symptoms. It is not expected in opioid or stimulant withdrawal.
E. Hyperreflexia: Increased reflexes can occur during stimulant withdrawal or opioid withdrawal due to central nervous system hyperactivity. The client’s restlessness and autonomic manifestations suggest this risk.
F. Hypothermia: Withdrawal typically causes hyperthermia or temperature instability rather than hypothermia. Low body temperature is not a typical manifestation in opioid or stimulant withdrawal.
