Your patient is allergic to penicillin. He may also have a cross-allergy to which class of antibiotics?

Aminoglycosides

Sulfonamides

Macrolides

Cephalosporins

Answer and Explanation

The Correct Answer is D

A. Aminoglycosides: Aminoglycosides are a separate class of antibiotics with a different chemical structure than penicillins. There is no known cross-allergy between penicillins and aminoglycosides.
B. Sulfonamides: Sulfonamides are also a different class of antibiotics, and there is no significant cross-allergy risk with penicillins. However, individuals with allergies to sulfonamide medications may have a higher risk of allergic reactions to other sulfonamide-containing drugs, but this is unrelated to penicillin allergy.
C. Macrolides: Macrolides, such as erythromycin and azithromycin, have a different chemical structure than penicillins, and cross-allergy between penicillins and macrolides is rare. They are considered alternative antibiotic options for patients with penicillin allergies.
D. Cephalosporins: Cephalosporins are a class of antibiotics structurally and chemically related to penicillins. There is a risk of cross-allergy between penicillins and cephalosporins due to their similar beta-lactam ring structure. However, the extent of cross-reactivity varies among different cephalosporins and individual patient sensitivities. It's essential to assess the severity of the penicillin allergy and consider alternative antibiotics if cross-allergy is a concern.

Correct Answer is D

Explanation

A. Ask the patient an open-ended question about feelings: This might reveal anxieties but not necessarily confirm understanding of the steps.
B. Ask the patient to repeat the information in the pamphlet: Repeating information doesn't guarantee comprehension of how to perform the task.
C. Have the patient list the steps: This can be helpful, but observing actual performance allows for correcting any errors in technique.
D. Observe as the patient prepares and injects a dose of insulin: Direct observation is the most reliable way to assess if the patient can safely and accurately self-administer insulin.

A. Insulin B. Growth hormone C. Estrogen D. Glucagon E. Antidiuretic hormone

Correct Answer is ["A","D"]

Explanation

A. Insulin: Insulin is produced by the beta cells of the pancreas and lowers blood glucose levels by facilitating the uptake of glucose into cells.
B. Growth hormone: Growth hormone is produced by the pituitary gland, not the pancreas. It can affect blood glucose levels indirectly but is not a pancreatic hormone.
C. Estrogen: Estrogen is produced primarily by the ovaries, not the pancreas. It does not directly regulate blood glucose levels.
D. Glucagon: Glucagon is produced by the alpha cells of the pancreas and raises blood glucose levels by promoting the conversion of glycogen to glucose in the liver.
E. Antidiuretic hormone: Antidiuretic hormone (ADH) is produced by the hypothalamus and released by the pituitary gland. It regulates water balance in the body, not blood glucose levels.
