A nurse is caring for a patient with decreased triiodothyronine (T3) and thyroxine (T4) and elevated thyroid-stimulating hormone (TSH) levels. The nurse knows the patient is likely suffering from what?

Hyperthyroidism

Hypothyroidism

Thyroid cancer

Pituitary adenoma

Answer and Explanation

The Correct Answer is B

Choice A reason: Hyperthyroidism involves elevated T3 and T4 with low TSH due to excessive thyroid hormone production. The patient’s low T3/T4 and high TSH indicate reduced thyroid activity, not overactivity, as the pituitary increases TSH to stimulate the underactive thyroid, making this choice incorrect.

Choice B reason: Hypothyroidism is characterized by low T3 and T4 levels due to underactive thyroid function, prompting the pituitary to secrete more TSH to stimulate hormone production. This matches the patient’s lab results (low T3/T4, high TSH), often seen in primary hypothyroidism, making this the correct choice.

Choice C reason: Thyroid cancer may alter thyroid function but typically doesn’t present with consistently low T3/T4 and high TSH. It’s more likely to cause nodules or abnormal growths, not this specific hormonal pattern, which aligns with hypothyroidism, making this choice less likely.

Choice D reason: Pituitary adenoma causing secondary hypothyroidism would lower TSH, T3, and T4 due to impaired pituitary function. High TSH with low T3/T4 suggests primary thyroid failure, not pituitary dysfunction, making this choice incorrect for the patient’s hormonal profile.

Correct Answer is ["A","B","C"]

Explanation

Choice A reason: Selectivity ensures a drug targets specific receptors, minimizing side effects. This is a key property of an ideal drug, making it a correct choice.

Choice B reason: Safety is critical, ensuring the drug causes minimal harm at therapeutic doses. This is a fundamental ideal drug property, so it is correct.

Choice C reason: Effectiveness ensures the drug achieves its intended therapeutic effect. This is essential for an ideal drug, making it a correct choice.

Choice D reason: Irreversible action is not ideal; reversible effects allow control and safety. The ‘Big Three’ focus on efficacy, safety, and selectivity, so this is incorrect.

Choice E reason: A trade name aids marketing but is not a pharmacological property. Effectiveness, safety, and selectivity are primary, so this is incorrect.

A. Using electronic medical order entry systems B. Naming, blaming, and shaming those who make errors C. Prosecuting caregivers who make errors D. Helping patients to be active, informed members of the healthcare team E. Developing nonpunitive approaches to track errors

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

Explanation

Choice A reason: Electronic order entry systems reduce errors by standardizing prescriptions and flagging issues. This enhances safety, making it a correct preventive strategy.

Choice B reason: Naming and shaming create fear, discouraging error reporting and learning. Nonpunitive approaches are effective, so this is incorrect for preventing errors.

Choice C reason: Prosecuting caregivers deters transparency, hindering error analysis. Supportive tracking systems prevent errors, so this is incorrect for effective strategies.

Choice D reason: Engaging patients as informed team members improves adherence and catches errors. This collaborative approach is effective, making it a correct choice.

Choice E reason: Nonpunitive error tracking encourages reporting, identifying patterns to prevent future mistakes. This is a proven method, making it a correct choice.
