Which statement best describes electrolytes in intracellular and extracellular fluid?
- A. There is a greater concentration of sodium in extracellular fluid and potassium in intracellular fluid
- B. There is an equal concentration of sodium and potassium in extracellular fluid
- C. There is a greater concentration of potassium in extracellular fluid and sodium in intracellular fluid
- D. There is an equal concentration of sodium and potassium between intracellular and extracellular fluid
Correct Answer: A
Rationale: Electrolytes are distributed unequally between intracellular and extracellular fluids. Sodium concentration is higher in extracellular fluid, while potassium concentration is higher in intracellular fluid. Therefore, the correct answer is 'There is a greater concentration of sodium in extracellular fluid and potassium in intracellular fluid.' Choices B, C, and D are incorrect because they do not accurately describe the typical distribution of sodium and potassium between intracellular and extracellular fluid.

A nurse has been ordered to administer Morphine to a patient. Which of the following effects is unrelated to Morphine's effects on the patient?
- A. Depressed function of the CNS
- B. Increased blood flow
- C. Decreased venous capacity
- D. Pain relief
Correct Answer: C
Rationale: Morphine is a narcotic analgesic that acts centrally to relieve pain by binding to opioid receptors in the CNS, leading to the depressed function of the CNS. Morphine also causes peripheral vasodilation, which can lead to increased blood flow. However, morphine causes venous dilation and increased venous capacity rather than decreased venous capacity. Therefore, the effect of 'Decreased venous capacity' is unrelated to Morphine's effects. Pain relief is a well-known effect of Morphine, as it acts on the CNS to alter the perception of pain.
A 27-year-old woman has delivered twins in the OB unit. The patient develops a condition of 5-centimeter diastasis recti abdominis. Which of the following statements is the most accurate when instructing the patient?
- A. Avoid sit-ups to prevent worsening the condition.
- B. Surgery is not always necessary for this condition.
- C. Guarding the abdominal region is important at this time.
- D. Antibiotics are not needed for diastasis recti abdominis.
Correct Answer: C
Rationale: After experiencing diastasis recti abdominis, it is crucial for the patient to protect and guard the abdominal region to facilitate healing. Choice A is correct since avoiding sit-ups is important to prevent worsening the condition by increasing intra-abdominal pressure. Choice B is accurate as not all cases of diastasis recti abdominis require surgery; conservative management is often effective. Choice D is also correct as antibiotics are not indicated for diastasis recti abdominis since it is a separation of the abdominal muscles and not an infectious condition.
A client receiving drug therapy with furosemide and digitalis requires careful observation and care. In planning care for this client, the nurse should recognize that which of the following electrolyte imbalances is most likely to occur?
- A. hyperkalemia
- B. hypernatremia
- C. hypokalemia
- D. hypomagnesemia
Correct Answer: C
Rationale: When a client is receiving drug therapy with furosemide and digitalis, the nurse should anticipate the development of hypokalemia due to the potassium-wasting effects of furosemide. Hypokalemia can potentiate digitalis toxicity. While hyperkalemia is a concern with some medications, it is not typically associated with furosemide and digitalis. Furosemide can lead to hyponatremia, not hypernatremia, due to its diuretic effect. Hypomagnesemia, though a possible imbalance, is not the most likely to occur in this scenario as furosemide and digitalis are more commonly associated with hypokalemia.
A 14-year-old boy has been admitted to a mental health unit for observation and treatment. The boy becomes agitated and starts yelling at nursing staff members. What should the nurse's first response be?
- A. Create an atmosphere of seclusion for the boy according to procedures.
- B. Remove other patients from the area for added safety.
- C. Ask the patient, "What is making you mad?"?
- D. Ask the patient, "Why are you behaving this way? Have you thought about what may help you calm down?"?
Correct Answer: A
Rationale: In a situation where a patient is agitated and yelling, the first response should be to create an atmosphere of seclusion for the safety of the patient and others. Seclusion is a standard procedure to help manage aggressive behaviors and prevent harm. Options B, C, and D are not appropriate in this scenario. Removing other patients may not address the immediate safety concern, asking the patient what is making them mad can escalate the situation, and questioning why the patient is behaving that way may not help in managing the current agitation. Therefore, seclusion is the recommended course of action in this scenario to ensure the safety and well-being of all involved.
When encountering the significant other of a patient with end-stage AIDS crying during her smoke break, what is the most appropriate action for the nurse to take?
- A. Allow her to grieve by herself.
- B. Tell her to go ahead and cry, after all, your husband’s pretty bad off.
- C. Tell her you realize how upset she is, but you don’t want to talk about it now.
- D. Approach her, offering tissues, and encourage her to verbalize her feelings
Correct Answer: D
Rationale: Approaching the significant other, offering tissues, and encouraging her to verbalize her feelings is the most appropriate action for the nurse to take. Being left alone during the grief process isolates individuals, and they need an outlet for their feelings. By showing empathy and providing support, the nurse can help the significant other cope with her emotions. Choices A, B, and C are inappropriate because they do not offer support or encourage the expression of feelings, which are crucial in such situations.
