Question 1 of 5
The patient is scheduled to have an EEG to confirm the presence of a sleep disorder. The patient asks the nurse to describe NREM stage 3 sleep. What is the best response by the nurse?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Which over-the-counter (OTC) antihistamine combination contains an analgesic property?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
What is the therapeutic use of Digoxin?
Correct Answer: A
Rationale: The therapeutic use of Digoxin is primarily to increase cardiac output and slow down the heart rate. Digoxin is a cardiac glycoside that works by increasing the force of the heart's contractions, thereby improving cardiac output in conditions such as heart failure. Additionally, it also helps to slow down the heart rate by affecting the electrical conduction system of the heart. This combination of effects makes Digoxin valuable in treating conditions like heart failure, atrial fibrillation, and atrial flutter.
Question 4 of 5
A 42-year-old man undergoes a neurologic evaluation because of episodes of apparent confusion. Over the past year, the man has experienced episodes during which he develops a blank look on his face and fails to respond to questions. Moreover, it appears to take several minutes before the man recovers from the episodes. Which one of the following best describes this type of seizure?
Correct Answer: B
Rationale: Focal complex partial seizures impair consciousness, causing confusion, unresponsiveness, and a blank stare, lasting minutes with slow recovery, as described. Simple partial seizures preserve awareness with focal symptoms.
Tonic-clonic seizures feature convulsions. Absence seizures are brief (seconds) with rapid recovery. Myoclonic seizures involve jerks. The prolonged duration and impaired consciousness align with complex partial seizures' temporal lobe origin and EEG findings, distinguishing it here.
Question 5 of 5
Which of the following statements regarding colloid administration does the nurse identify as being true?
Correct Answer: A
Rationale: Colloids, such as albumin and synthetic colloids like hydroxyethyl starch, do not enhance the oxygen-carrying capacity of the blood. They can help to increase the intravascular volume in cases of hypovolemia by osmotically drawing fluid into the intravascular space. This can help improve tissue perfusion by increasing blood pressure. Colloids do not have a direct effect on oxygen-carrying capacity or coagulation properties. Dextran therapy can cause adverse effects like anaphylaxis or renal failure, but it is not a general contraindication for all colloid administration in the treatment of hypovolemia.
