A patient with chronic kidney disease is at risk for developing which of the following electrolyte imbalances?

A. Decrease in the concentration of calcium in the glomerulus.

B. Increase in the concentration of potassium in the blood.

C. Decrease in the concentration of sodium in the blood.

D. Increase in the concentration of magnesium in the blood.

Answer Explanation:

The correct answer is choice B.

A patient with chronic kidney disease is at risk for developing an increase in the concentration of potassium in the blood.

The kidneys play a pivotal role in the regulation of electrolyte balance.

With progressive loss of kidney function, derangements in electrolytes inevitably occur and contribute to poor patient outcomes123.

Choice A is incorrect because calcium concentration is not regulated in the glomerulus.

Choice C is incorrect because chronic kidney disease can result in either an increase or decrease in sodium concentration in the blood.

Choice D is incorrect because chronic kidney disease does not necessarily result in an increase in magnesium concentration in the blood.

Therefore, the Correct Answer is B.

  • Q #1: A nurse is caring for a patient who has been declared brain dead and is awaiting organ donation. Which of the following interventions is most important to preserve the viability of the organs?

    A. Administering antibiotics to prevent infection.

    B. Maintaining normal body temperature and blood pressure.

    C. Providing emotional support to the family members.

    D. Applying eye drops and ointment to prevent corneal drying.

    Answer Explanation

    The correct answer is choice B.

    Maintaining normal body temperature and blood pressure.

    Early identification and management of potential organ donors must take into consideration specific pathophysiologic changes for medical optimization 1.

    The VIPPS (ventilation, infusion and pumping, pharmacological treatment, and specificities) strategy is a mnemonic method that brings together key aspects of the restoration of oxygen delivery to tissues during hemodynamic instability plus organ optimization strategies.

    Choice A is incorrect because administering antibiotics to prevent infection is not the most important intervention to preserve organ viability.

    Choice C is incorrect because providing emotional support to family members, while important, is not an intervention that directly affects organ viability.

    Choice D is incorrect because applying eye drops and ointment to prevent corneal drying is not the most important intervention to preserve organ viability.

  • Q #2: Which hormone is responsible for the development of female secondary sexual characteristics such as breast development, menstrual cycle, and widening of hips?

    A. Progesterone

    B. Testosterone

    C. Estrogen

    D. FSH

    Answer Explanation

    The correct answer is choice C. Estrogen.

    Estrogen is a steroid hormone responsible for the development of female secondary sexual characteristics such as breast development, menstrual cycle, and widening of hips.

    Choice A, Progesterone, is not the correct answer because it is required to maintain pregnancy and delivery.

    Choice B, Testosterone, is not the correct answer because it is a hormone produced by the testes which controls the development of male secondary sexual characteristics.

    Choice D, FSH (Follicle Stimulating Hormone), is not the correct answer because it stimulates the growth of ovarian follicles in females and regulates spermatogenesis in males.

  • Q #3: Which gland, located in the mediastinum, plays a key role in the development and maturation of T-lymphocytes?

    A. Thymus

    B. Parathyroid

    C. Adrenal

    D. Pituitary

    Answer Explanation

    The correct answer is choice A. Thymus.

    The thymus is a primary lymphoid organ located in the mediastinum.

    It plays a key role in the maturation and differentiation of T-lymphocytes.

     

    Choice B.

    Parathyroid is incorrect because the parathyroid glands are small endocrine glands located in the neck that produce parathyroid hormone, which regulates calcium levels in the blood.

    Choice C.

    Adrenal is incorrect because the adrenal glands are endocrine glands located above the kidneys that produce hormones such as cortisol and adrenaline.

    Choice D.

    Pituitary is incorrect because the pituitary gland is an endocrine gland located at the base of the brain that produces hormones that regulate growth, metabolism, and reproductive functions.
