The onset of ICU psychosis is:
Usually rapid and very upsetting to patient and family members
Consciousness remains stable
Symptoms are the same with each patient experiencing ICU psychosis
Usually gradual and increases with length of stay and very upsetting to patient and family members
The Correct Answer is A
Rationale:
A. Usually rapid and very upsetting to patient and family members is correct because ICU psychosis (delirium) often has a sudden onset, with patients experiencing acute confusion, disorientation, agitation, hallucinations, or delusions. This abrupt change is distressing for both the patient and their family, requiring prompt recognition and management.
B. Consciousness remains stable is incorrect because ICU psychosis is characterized by fluctuating levels of consciousness and attention, not stable awareness. Patients may alternate between hyperactive, hypoactive, or mixed delirium states.
C. Symptoms are the same with each patient experiencing ICU psychosis is incorrect because ICU delirium presents variably. Some patients may be agitated and combative, while others are quiet and withdrawn, making it essential for nurses to assess each patient individually.
D. Usually gradual and increases with length of stay and very upsetting to patient and family members is incorrect because the onset is typically rapid, not gradual. While prolonged ICU stay is a risk factor for delirium, the initial presentation is sudden rather than slowly progressive

Correct Answer is D
Explanation
Rationale:
A. This is incorrect because hand hygiene is the most critical intervention to prevent infection in immunosuppressed patients. Staff should strictly wash hands before and after all patient contact. Omitting hand washing would increase the risk of life-threatening infections.
B. This is incorrect because antimicrobial soaps are safe and often recommended for bathing immunosuppressed patients to reduce the risk of infection. Avoiding them could increase susceptibility to pathogens.
C. This is incorrect because placing multiple intravenous lines unnecessarily increases the risk of infection and does not prevent immunosuppression-related complications. IV lines should only be used as clinically indicated.
D. This is correct because placing the patient in a single room with HEPA filtration helps reduce exposure to airborne pathogens, which is essential for severely immunocompromised patients, such as those undergoing chemotherapy. Additional precautions include limiting visitors, using protective equipment, and maintaining strict aseptic technique during procedures.
Correct Answer is D
Explanation
Rationale:
A. 25 kcal/kg/day – Partially correct but represents the lower end of the range and may not meet needs for all mildly stressed patients.
B. 30–35 kcal/kg/day – Incorrect for mild stress; this range is more appropriate for moderate to severe stress or hypermetabolic states.
C. 40 kcal/kg/day – excessive for mild stress and may contribute to overfeeding complications.
D. 25–30 kcal/kg/day – Caloric requirements for critically ill patients vary depending on the level of metabolic stress. Mildly stressed patients generally require 25–30 kcal/kg/day to maintain energy balance and support healing. This range accounts for the increased metabolic demands without overfeeding, which can lead to complications such as hyperglycemia or increased CO₂ production.
