A 49-year-old man who has type 2 diabetes, high blood pressure, hyperlipidemia, and gastroesophageal reflux tells the nurse that he has had recent difficulty in achieving an erection.
Which of the following drugs from his current medications list may cause erectile dysfunction (ED)?
Propranolol (Inderal)
Ranitidine (Zantac)
Atorvastatin (Lipitor)
Metformin (Glucophage)
The Correct Answer is A
Choice A rationale: Propranolol, a beta-blocker used for high blood pressure and other cardiovascular conditions, is known to have potential side effects of sexual dysfunction, including erectile dysfunction (ED).
Choice B rationale: Ranitidine (Zantac) is an H2 blocker used for acid reflux and isn't typically associated with causing ED.
Choice C rationale: Atorvastatin (Lipitor), a statin used for high cholesterol, isn't commonly associated with causing ED.
Choice D rationale: Metformin (Glucophage), used for type 2 diabetes, is not typically linked to causing ED.

Correct Answer is A
Explanation
Choice A rationale: The correct answer is 5 units/hour. To calculate the units of insulin per hour, we need to use the following formula: units of insulin per hour = (units of insulin in the bag / volume of the bag) x infusion rate
Plugging in the given values, we get:
units of insulin per hour = (50 / 100) x 10 units of insulin per hour = 0.5 x 10
units of insulin per hour = 5
Therefore, the client is receiving 5 units of insulin every hour.
Choice B rationale: This is incorrect because it assumes that the infusion rate is equal to the units of insulin per hour, which is not true.
Choice C rationale: This is incorrect because it multiplies the units of insulin in the bag by the infusion rate, which is too high.
Choice D rationale: This is incorrect because it adds the units of insulin in the bag and the infusion rate, which is also too high.
Correct Answer is C
Explanation
Choice A rationale: Irregular respirations, bradycardia, and widened pulse pressure might indicate increased intracranial pressure.
Choice B rationale: This set of symptoms is often seen in cardiac tamponade and is referred to as the Beck’s triad and not Cushing's triad.
Choice C rationale: Cushing's triad is a set of clinical signs associated with increased intracranial pressure (ICP) and typically includes bradycardia (slow heart rate),
hypertension (elevated blood pressure), and irregular breathing patterns. Fixed pupils can also be present in some cases, but it's important to note that this triad is not always consistently present and may vary from person to person.
Choice D rationale: This set of symptoms describes symptoms of shock, not specifically Cushing's triad.
