Pharmacology for NursesReview Questions
1.
A nurse is preparing to teach a client about temperature regulation and homeostasis. Which statement should the nurse include in the teaching plan?
  1. Homeostasis makes your blood pressure rise when you experience stress.
  2. Homeostasis allows you to maintain a stable body temperature despite the outside temperature.
  3. Homeostasis is solely under the control of your brain and nervous system.
  4. Homeostasis converts food into energy.
2.
The nurse is caring for a client with a high serum osmolality. Which condition is the client likely to have?
  1. Dehydration
  2. Fluid volume excess
  3. Hypothermia
  4. Hyperkalemia
3.
The nurse is caring for a client with excessive fluid accumulation in the pleural cavity. The nurse determines that fluid is accumulating in which fluid compartment?
  1. Intracellular
  2. Extracellular
  3. Interstitial
  4. Transcellular
4.
The nurse is caring for a client who has been experiencing diarrhea. Which anion does the nurse anticipate the client is losing through this loss of extracellular fluid?
  1. Calcium
  2. Sodium
  3. Potassium
  4. Chloride
5.
The nurse is caring for a client with a gastrointestinal hemorrhage. Which fluid compartment does the nurse understand is losing fluid?
  1. Interstitial compartment
  2. Intravascular compartment
  3. Transcellular compartment
  4. Intracellular compartment
6.
A nurse is caring for a pregnant client who is in labor. Which of the following statements accurately describes the concept of positive feedback in the context of labor?
  1. Oxytocin is suppressed, stimulating uterine contractions.
  2. Oxytocin is released, stimulating uterine contractions.
  3. Oxytocin is suppressed, increasing contractions.
  4. Oxytocin is released, halting uterine contractions.
7.
A nurse is teaching a group of nursing students about the Na+K+ATPase pump. Which of the following statements accurately describes the role of this pump in maintaining cellular function?
  1. Potassium moves out of the cell and sodium moves into the cell, thereby maintaining a higher concentration of potassium inside the cell.
  2. Sodium moves out of the cell and potassium moves into the cell, thereby maintaining a higher concentration of sodium inside the cell.
  3. Sodium and potassium move out of the cell, thereby maintaining an equal concentration of electrolytes inside and outside the cell.
  4. Sodium and potassium move into the cell, thereby maintaining a higher concentration of electrolytes outside the cell.
8.
Which of the following is an example of a negative feedback loop in the human body?
  1. Release of oxytocin during childbirth
  2. Blood clotting
  3. Lactation
  4. Regulation of blood glucose levels
9.
The nurse is caring for a client with a fluid imbalance. Which statement accurately describes the distribution of intracellular (ICF) and extracellular fluid (ECF) in the body?
  1. The ICF constitutes approximately 40% of total body fluid, and ECF accounts for 20%.
  2. The ICF constitutes approximately 40% of total body fluid, and ECF accounts for 60%.
  3. The ICF constitutes approximately 20% of total body fluid, and ECF accounts for 80%.
  4. The ICF constitutes approximately 80% of total body fluid, and ECF accounts for 20%.
10.
Which of the following best describes the concept of osmotic equilibrium in the body?
  1. The balance of water and electrolytes in the body
  2. The balance of water and solutes across a semipermeable membrane
  3. The balance of ions in the body’s extracellular and intracellular fluid compartments
  4. The balance of acids and bases in the body’s fluid
