A goiter is an enlargement or hypertrophy of which gland?

Thyroid.

Posterior pituitary.

Adrenal.

Anterior pituitary.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

A goiter refers to the enlargement or hypertrophy of the thyroid gland. This can occur due to various reasons, such as iodine deficiency, autoimmune disorders like Hashimoto's thyroiditis, or Graves' disease (which is associated with hyperthyroidism). The thyroid gland produces hormones that regulate metabolism and growth, and when it becomes enlarged, it can lead to visible swelling in the neck.

Choice B rationale:

The posterior pituitary gland is responsible for the release of hormones like vasopressin (antidiuretic hormone) and oxytocin. A goiter is not associated with the posterior pituitary gland. Issues with the posterior pituitary can lead to problems with water balance and uterine contractions, but not thyroid enlargement.

Choice C rationale:

The adrenal glands are responsible for producing hormones like cortisol and adrenaline. While adrenal disorders can lead to various hormonal imbalances, a goiter is not related to adrenal gland function. Adrenal issues might cause symptoms like fatigue, weight changes, and blood pressure irregularities.

Choice D rationale:

The anterior pituitary gland produces hormones that regulate the functions of other endocrine glands, including the thyroid gland. However, a goiter is not directly associated with the anterior pituitary. The anterior pituitary's malfunction can result in disorders like growth hormone deficiency or Cushing's disease, but not thyroid enlargement.

Correct Answer is B

Explanation

The correct answer is choice B: "I have to stay on strict bed rest for 3 days."

Choice A rationale:

The statement "I should avoid tub baths but may shower" is correct. After a cardiac catheterization, the patient needs to keep the insertion site clean and dry to prevent infection. Showering is allowed, but tub baths should be avoided to minimize the risk of introducing water into the insertion site.

Choice B rationale:

The statement "I have to stay on strict bed rest for 3 days" is incorrect. Bed rest is not typically required after a cardiac catheterization. While the patient might need to lie flat for a few hours after the procedure to prevent bleeding and ensure hemostasis, strict bed rest for three days is unnecessary and could lead to complications like deep vein thrombosis (DVT) or deconditioning.

Choice C rationale:

The statement "I may attend school but should avoid exercise for several days" is correct. Attending school is generally acceptable after a cardiac catheterization, but exercise should be limited for several days to allow the insertion site to heal and to prevent complications like bleeding or hematoma formation.

Choice D rationale:

The statement "I should remove the pressure dressing the day after the procedure" is correct. Pressure dressings are typically removed by healthcare professionals after a specified period, which is usually around 24 hours after the procedure. Removing the dressing on their own the day after the procedure could lead to disruption of the wound and increase the risk of infection.

A. Decreased urinary output. B. Sweating (inappropriate). C. Warm flushed extremities. D. Anorexia. E. Weight loss.

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

Explanation

The correct answers are choices A, B, and D.

Choice A rationale:

Decreased urinary output can be a sign of heart failure, especially in infants. In heart failure, the heart's ability to pump effectively can lead to decreased blood flow to the kidneys, resulting in decreased urine production.

Choice B rationale:

Sweating (inappropriate) is a symptom of heart failure in infants. Infants with heart failure might sweat excessively, especially while feeding or crying, due to the effort required by the heart to pump blood effectively.

Choice C rationale:

Warm flushed extremities are not typically associated with heart failure in infants. In heart failure, extremities might actually become cool and pale due to poor circulation.

Choice D rationale:

Anorexia, or a lack of appetite, is a common sign in infants with heart failure. The increased effort required for feeding due to compromised cardiac function can lead to poor feeding and decreased appetite.

Choice E rationale:

Weight loss can occur in infants with heart failure due to inadequate caloric intake, difficulty with feeding, and increased metabolic demands associated with heart failure. However, it's not as specific a sign as decreased urinary output, sweating, and anorexia.
