A client is admitted to the hospital and will be undergoing tests to determine if an abdominal mass is present. What should the nurse be sure to document when asking about allergies?
- A. If the client is allergic to beef
- B. If the client is allergic to pork
- C. If the client is allergic to shellfish
- D. If the client is allergic to grapefruit
Correct Answer: C
Rationale: The nurse must document allergies to iodine or shellfish, as these can react with contrast dyes used in imaging tests for abdominal masses. Allergies to beef, pork, or grapefruit are not relevant to contrast dye safety.

A group of students is reviewing for a test on hormones. The students demonstrate understanding of the material when they state which of the following as being secreted by the kidneys?
- A. Atrial natriuretic peptide
- B. Estrogen
- C. Renin
- D. Gastrin
Correct Answer: C
Rationale: The kidneys release renin and erythropoietin. Atrial natriuretic peptide is secreted by the atria of the heart, estrogen by the ovaries and placenta during pregnancy, and gastrin by the stomach to increase hydrochloric acid production.
The nurse should inform the client that oxytocin's function in the body is to do what?
- A. It causes production and secretion of thyroid hormones.
- B. It increases blood calcium by stimulating calcium release from the bone and decreases the blood phosphate level.
- C. It stimulates bone and muscle growth and promotes protein synthesis and fat mobilization.
- D. It stimulates the contraction of the pregnant uterus before birth and stimulates the release of breast milk after childbirth.
Correct Answer: D
Rationale: Oxytocin, secreted by the posterior pituitary, stimulates uterine contractions during labor and breast milk release postpartum. The other options describe functions of thyroid-stimulating hormone, parathyroid hormone, and somatotropin, respectively.
The nurse is caring for a client with an immunodeficiency disorder. Lab results show that the client does not have an adequate number of T lymphocytes needed to improve immune function. Which gland should be investigated for dysfunction?
- A. Thymus
- B. Parathyroid
- C. Thyroid
- D. Adrenal
Correct Answer: A
Rationale: The thymus gland secretes thymosin and thymopoietin, which are essential for T lymphocyte development, critical for immune function. The parathyroid, thyroid, and adrenal glands do not directly influence T lymphocyte production.
A client is scheduled for a diagnostic test to measure blood hormone levels. The nurse expects that this test will determine which of the following?
- A. The concentration of a substance in plasma
- B. Details about the size of the organ and its location
- C. The functioning of endocrine glands
- D. The client's blood sugar level
Correct Answer: C
Rationale: Measuring blood hormone levels helps determine the functioning of endocrine glands. A radioimmunoassay determines the concentration of substances in plasma, while radiographs assess organ size and location. Blood sugar levels are measured separately, typically for diabetes management.
A nurse is reading an article that describes the function of the neurohypophysis. The nurse identifies this structure as part of which of the following?
- A. Hypothalamus
- B. Pineal gland
- C. Posterior pituitary
- D. Thymus gland
Correct Answer: C
Rationale: The neurohypophysis refers to the posterior lobe of the pituitary gland, which releases oxytocin and antidiuretic hormone. The hypothalamus influences the pituitary, the pineal gland secretes melatonin, and the thymus gland supports T lymphocyte production.
