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 D
Explanation
Choice A rationale: This is not the accurate amount of fluid intake by the patient.
Choice B rationale: This is less than the total fluid intake by the patient.
Choice C rationale: This is less than the total fluid intake by the patient.
Choice D rationale: This is correct.( This is the sum of the intravenous fluid, the water, and the chicken broth, converted to milliliters: 650 + (6 x 30) + (8 x 30) = 1070.)
Correct Answer is C
Explanation
Choice A rationale: Low blood pressure sensed by baroreceptors in the kidneys would stimulate the renin-angiotensin-aldosterone system, which regulates blood pressure and sodium balance.
Choice B rationale: Low osmolality sensed by osmoreceptors in the kidneys would
indicate that the body has excess water and needs to excrete it, which would inhibit ADH release.
Choice C rationale: ADH, or antidiuretic hormone, is a peptide hormone that regulates the water balance in the body. It is released from the posterior pituitary gland in response to signals from the hypothalamus. When the plasma osmolarity, or the concentration of solutes in the blood, is high, it means that the body is dehydrated and needs to conserve water. The osmoreceptors in the hypothalamus detect this change and stimulate the release of ADH, which acts on the kidneys to increase water
reabsorption and decrease urine output. This helps to lower the plasma osmolarity and restore the water balance.
Choice D rationale: High concentration of potassium sensed by chemoreceptors in the carotid body would affect the acid-base balance and respiratory rate, but not ADH
release.
