Correct Answer: B

Rationale: Reverse isolation precautions protect the client from exposure to microorganisms from others.

Correct Answer: B

Rationale: A serum glucose level of 600 mg/dL is extremely high in a client with hyperosmolar hyperglycemic state (HHS) and poses a significant risk of serious complications such as dehydration, coma, and electrolyte imbalances. Rapid intervention is crucial to normalize the glucose level and prevent further deterioration. Serum osmolality of 320 mOsm/kg, serum potassium of 4.5 mEq/L, and serum sodium of 140 mEq/L, while important to monitor in HHS, do not represent an immediate life-threatening condition that requires urgent intervention compared to the critically high glucose level.

Correct Answer: C

Rationale: A respiratory rate of 26 breaths per minute is an abnormal finding and indicates that the client is experiencing respiratory distress, requiring immediate intervention. This rapid respiratory rate can signify inadequate oxygenation and ventilation. Oxygen saturation of 88% is low but not as immediately concerning as a high respiratory rate, which indicates the body is compensating for respiratory distress. The use of accessory muscles for breathing and a barrel-shaped chest are typical findings in clients with COPD but do not indicate an immediate need for intervention as they are more chronic in nature and may be seen in stable COPD patients.

Correct Answer: C

Rationale: Administering the medication with a small amount of pudding helps prevent aspiration in clients with dysphagia.

Correct Answer: B

Rationale: Low blood pressure in a client with Addison's disease requires immediate intervention as it can indicate an Addisonian crisis, a life-threatening condition that necessitates prompt treatment. Hyperpigmentation of the skin is a characteristic finding in Addison's disease but does not require immediate intervention. Nausea and vomiting can be managed symptomatically in Addison's disease. While hypoglycemia needs attention, it is not the most critical finding requiring immediate intervention in this context.
