Question 1 of 5
Which is the only type of insulin that can be given IV?
Correct Answer: A
Rationale: Regular insulin is the only type of insulin that can be given intravenously (IV) due to its short onset of action. When administered IV, regular insulin can act quickly to control blood sugar levels in emergency situations such as diabetic ketoacidosis (DKA) or hyperglycemic crises. Other types of insulin, such as NPH, long-acting, or rapid-acting insulins, are not suitable for IV administration as they have different pharmacokinetic properties and are designed for subcutaneous use.
Question 2 of 5
A client calls the nurse help-line and says, 'My friend and I have been swimming and drinking beer all day and he took a couple of swigs of Robitussin DM (dextromethorphan) about 15 minutes ago. Now he is acting funny and seeing things.' What should the nurse consider when formulating a response?
Correct Answer: D
Rationale: Dextromethorphan (DM), a cough suppressant, can cause dizziness, hallucinations, and confusion, especially with alcohol, which amplifies CNS depression . Dialysis isn't standard for DM overdose; it's not an opioid , though it acts centrally; and addiction isn't the acute issue. The nurse considers dizziness as a key adverse effect, worsened by beer, guiding a response to seek medical help.
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
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: NREM stage 3, deep sleep, restores energy-lack causes fatigue and mood dips, per sleep physiology. Stage 1 is lightest, anxiety-sensitive. Dreaming is REM, not here-irritability ties to REM loss. Paradoxical is REM. Deep sleep's role explains EEG focus, answering accurately.
Question 5 of 5
A male patient has been started on a 5-alpha reductase inhibitor for the treatment of benign prostatic hyperplasia (BPH). Which information should the nurse provide?
Correct Answer: A
Rationale: 5-alpha reductase inhibitors like finasteride for benign prostatic hyperplasia (BPH) require condom use during intercourse because the drug, present in semen, poses a teratogenic risk to a pregnant partner, potentially causing fetal abnormalities. Storing it securely protects children from exposure, as it's hazardous to developing systems. Blood donation is prohibited during and shortly after use due to residual drug in plasma, risking harm to recipients, especially pregnant women. Heavy exercise isn't restricted-activity doesn't alter its efficacy or safety. Condom use is a priority education point, directly addressing reproductive safety, a unique concern tied to its mechanism and pharmacokinetics.
