Which are conditions that may be treated using beta blockers? (Select all that apply.)

Cardiac dysrhythmias

Hypotension

Hypothyroidism

Heart failure

Stage fright

Answer and Explanation

Correct Answer : A,D,E

Choice A reason: Beta blockers are commonly used to treat cardiac dysrhythmias (irregular heartbeats). They work by blocking the effects of adrenaline on the heart, which helps to reduce the heart rate and regulate the rhythm. This makes beta blockers effective in managing conditions such as atrial fibrillation, ventricular arrhythmias, and supraventricular tachycardia.

Choice B reason: Hypotension (low blood pressure) is not typically treated with beta blockers. In fact, beta blockers can sometimes lower blood pressure, so they are usually avoided in patients with pre-existing hypotension. Instead, other medications or treatments are used to manage low blood pressure.

Choice C reason: Hypothyroidism (underactive thyroid) is not treated with beta blockers. The primary treatment for hypothyroidism is thyroid hormone replacement therapy, usually with levothyroxine. Beta blockers do not address the underlying issue of thyroid hormone deficiency and are not used in the management of this condition.

Choice D reason: Beta blockers are used to treat heart failure, particularly in patients with systolic heart failure. They help to reduce the workload on the heart, improve heart function, and decrease the risk of hospitalization and mortality. By slowing the heart rate and reducing the force of contraction, beta blockers can help to manage symptoms and improve outcomes in heart failure patients.

Choice E reason: Beta blockers are used to treat stage fright (performance anxiety) because they help to control physical symptoms of anxiety, such as rapid heart rate, trembling, and sweating. By blocking the effects of adrenaline, beta blockers can help individuals feel calmer and more composed during stressful situations, such as public speaking or performing in front of an audience.

Correct Answer is B

Explanation

Choice A reason: There is not a 25% chance that the offspring will be a carrier. In the case of recessive disorders, if one parent is affected (homozygous recessive) and the other parent is a carrier (heterozygous), the offspring has a different probability of being a carrier or affected.

Choice B reason: There is a 50% chance that the offspring will be a carrier. If the mother is affected (aa) and the father is a carrier (Aa), each child has a 50% chance of inheriting one recessive allele (a) from the mother and one normal allele (A) from the father, making them a carrier (Aa).

Choice C reason: There is not a 75% chance that the offspring will be a carrier. The probability of the offspring being a carrier or affected follows specific Mendelian inheritance patterns, which do not result in a 75% carrier rate.

Choice D reason: There is not a 100% chance that the offspring will be a carrier. While there is a significant likelihood of the offspring being affected or a carrier, it is not guaranteed that all offspring will be carriers.

A. Nonadherence to the antiviral regimen. B. Pancreatic infiltration by HIV. C. Allergic reaction. D. Hyperglycemia.

Correct Answer is D

Explanation

Choice A reason: Nonadherence to the antiviral regimen could lead to a resurgence of HIV symptoms and a higher viral load, but it is not typically associated with the symptoms of increased hunger, thirst, and frequent urination described by the patient.

Choice B reason: Pancreatic infiltration by HIV is a rare complication and would not be the first suspicion in this scenario. While HIV can affect multiple organs, the symptoms described are more suggestive of metabolic issues rather than direct infiltration of the pancreas.

Choice C reason: An allergic reaction to the medication would more likely present with symptoms such as rash, itching, swelling, or difficulty breathing rather than the metabolic symptoms described. Allergic reactions typically do not cause increased hunger, thirst, or frequent urination.

Choice D reason: Hyperglycemia (high blood sugar levels) is the most likely cause of the symptoms described. Protease inhibitors can lead to metabolic side effects, including insulin resistance and hyperglycemia. Symptoms of hyperglycemia include increased hunger (polyphagia), increased thirst (polydipsia), and frequent urination (polyuria). These findings are consistent with the patient's complaints and should be investigated further to manage the side effects of the medication.
