Ipratropium is a synthetic bronchodilator atropine substitute administered by:

  • A. Oral route
  • B. Intravenous injection
  • C. Subcutaneous injection
  • D. Inhalation
Correct Answer: D

Rationale: The correct answer is D: Inhalation. Ipratropium is a bronchodilator used to treat conditions like asthma and chronic obstructive pulmonary disease (COPD). Inhalation allows direct delivery to the lungs, where it acts locally to relax the smooth muscle and dilate the airways, providing rapid relief of bronchospasm. Oral route (A) would result in poor absorption and systemic side effects. Intravenous (B) and subcutaneous (C) injections are not preferred due to the risk of systemic effects and lack of targeted action. Thus, inhalation is the most effective and appropriate route for ipratropium administration.

In evaluating the effectiveness of a new insulin dosage for a diabetic patient, the nurse would

  • A. check the urine for sugar and acetone
  • B. collect a 24-hour urine specimen for acetone determination

Where Are Islets of Langerhans Found?

  • A. Anterior pituitary
  • B. Cortex
  • C. Spleen
  • D. Endocrine pancreas
Correct Answer: D

Rationale: The Islets of Langerhans are clusters of cells in the pancreas that regulate blood sugar levels. Choice D, Endocrine pancreas, is correct because the Islets of Langerhans are specifically located in the pancreas. Choices A, B, and C are incorrect because the Islets of Langerhans are not found in the anterior pituitary, cortex, or spleen. The pancreas is the primary organ associated with blood sugar regulation, making it the correct location for the Islets of Langerhans.

All of the following are hormones of the anterior pituitary except:

  • A. Growth hormone
  • B. Follicle stimulating hormone
  • C. Parthormone
  • D. Thyroid stimulating hormone
Correct Answer: C

Rationale: The correct answer is C: Parthormone. The anterior pituitary gland secretes hormones such as Growth hormone, Follicle stimulating hormone, and Thyroid stimulating hormone, but not Parthormone. Parthormone is actually produced by the parathyroid glands, not the anterior pituitary gland. Parathormone plays a key role in regulating calcium levels in the blood. Therefore, choice C is incorrect as it does not belong to the hormones secreted by the anterior pituitary gland.

____________ is a steroid hormone.

  • A. Vitamin D
  • B. Epinephrine
  • C. Insulin
  • D. all of these
Correct Answer: A

Rationale: Vitamin D is the correct answer as it is a steroid hormone synthesized from cholesterol. Steroid hormones are derived from cholesterol and have a similar chemical structure. Epinephrine and Insulin are not steroid hormones. Epinephrine is a catecholamine produced by the adrenal glands, and Insulin is a peptide hormone produced by the pancreas. Choice D is incorrect as not all options listed are steroid hormones.

You are providing care for a patient who underwent thyroidectomy 2 days ago. Which laboratory value requires close monitoring?

  • A. Calcium
  • B. Sodium
  • C. Potassium
  • D. White blood cells
Correct Answer: A

Rationale: Calcium levels should be closely monitored after a thyroidectomy due to the risk of hypocalcemia caused by damage or removal of the parathyroid glands.
