Correct Answer: A

Rationale: In this scenario, the client is exhibiting Cheyne-Stokes respirations, which are characterized by periods of deep breathing alternating with apnea. This pattern indicates respiratory insufficiency, resulting in an accumulation of carbon dioxide in the blood. The elevated BP and slow heart rate further support the respiratory insufficiency, leading to respiratory acidosis. Therefore, the correct answer is Respiratory acidosis. Choices B, C, and D are incorrect. Respiratory alkalosis is characterized by decreased carbon dioxide levels in the blood, which is not indicated by the client's presentation. Metabolic acidosis results from conditions such as renal failure or diabetic ketoacidosis and is not the primary imbalance in this case. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels, which are not present in the client's vital signs.

Correct Answer: C

Rationale: The client taking Antabuse should avoid foods that contain alcohol or vinegar as they can trigger a disulfiram reaction. Pickles and vinaigrette dressing often contain vinegar, which the client should avoid. Beef is safe to consume. Choices A, B, and D do not contain alcohol or vinegar, so they are allowed for the client taking Antabuse.

Correct Answer: C

Rationale: When the nurse notes scabbing at the edges and a black collection of blood, it indicates the presence of debris that needs to be addressed. Leaving the scabbed area alone and applying extra ointment may not address the underlying issue and could lead to complications. Notifying the physician is important in some cases, but immediate action is required to prevent infection in this situation. Gently removing the debris and re-dressing the wound is the correct course of action to promote healing and prevent complications.

Correct Answer: B

Rationale: The most significant information to gather when a client is scheduled for platelet pheresis is the date of their last platelet donation. Platelet donors can typically have their platelets apheresed as frequently as every 14 days. Knowing the date of the last donation helps ensure the client is eligible for the procedure without risking any adverse effects from frequent donations. Allergies to shellfish may be important for other procedures where anticoagulants containing heparin are used, but it is not directly related to platelet pheresis. The time of the last oral intake is more crucial for procedures requiring sedation or anesthesia. Blood type is significant for blood transfusions but is not the primary concern for platelet pheresis.

Correct Answer: C

Rationale: The correct answer is Beta blockers. Beta blockers are commonly used to help decrease tremors in clients with hyperthyroidism by blocking the action of adrenaline. This helps to control symptoms such as rapid heart rate, tremors, and anxiety. Steroids (Choice A) are not typically used to treat tremors in hyperthyroidism. Anticonvulsants (Choice B) are primarily used to control seizures and are not the first-line treatment for tremors in hyperthyroidism. Iodine compounds (Choice D) are used in the treatment of hyperthyroidism by reducing the production of thyroid hormones but are not specifically indicated for tremor relief.
