1. How is the equalization of solute concentration of intracellular fluids (ICFs) and extracellular fluids (ECFs accomplished?
- A. Semipermeable membranes.
- B. Hydration.
- C. Osmotic pressure.
- D. Perspiration.
Correct answer: C
Rationale: The correct answer is C, osmotic pressure. Osmotic pressure within the body equalizes the solute concentration of ICFs and ECFs by shifting small amounts of water in the direction of higher concentration solute. Semipermeable membranes separate one fluid compartment from another and do not directly equalize solute concentrations. Hydration and perspiration are important elements of fluid balance but do not directly achieve the equalization of solute concentrations between ICFs and ECFs, which is primarily regulated by osmotic pressure.
2. A nurse orienting a newly licensed nurse is reviewing the procedure for taking a telephone prescription. Which of the following statements should the nurse identify as an indication that the newly licensed nurse understands the process?
- A. A second nurse enters the prescription into the client's medical record.
- B. Another nurse should listen to the phone call.
- C. The provider can clarify the prescription when he signs the health record.
- D. I should omit the 'read back' if this is a one-time prescription.
Correct answer: B
Rationale: The correct answer is B: 'Another nurse should listen to the phone call.' When taking a telephone prescription, having another nurse listen to the phone call is essential to prevent errors in communication. This process helps ensure accuracy and reduces the risk of misinterpretation. Choice A is incorrect because entering the prescription into the client's medical record is not related to verifying the accuracy of the telephone prescription. Choice C is incorrect as the provider clarifying the prescription upon signing the health record doesn't address the immediate need for verification during the phone call. Choice D is incorrect because the 'read back' is a crucial step in confirming the accuracy of all prescriptions, regardless of whether they are one-time or recurring.
3. The client on digoxin has a potassium level of 2.7 mEq/L. What is the nurse’s priority action?
- A. Hold the digoxin and notify the healthcare provider.
- B. Administer the digoxin as ordered.
- C. Increase the dose of digoxin.
- D. Administer potassium supplements.
Correct answer: A
Rationale: The correct answer is to hold the digoxin and notify the healthcare provider. A potassium level of 2.7 mEq/L is considered low and can increase the risk of digoxin toxicity. Holding the medication and informing the healthcare provider is crucial to prevent adverse effects. Administering the digoxin as ordered (Choice B) would put the client at a higher risk for toxicity. Increasing the dose of digoxin (Choice C) is not appropriate when the client's potassium level is low. Administering potassium supplements (Choice D) may be necessary but is not the priority action in this situation.
4. A nurse is caring for a client who has not voided for 8 hours following the removal of an indwelling urinary catheter. Which of the following actions should the nurse take first?
- A. Provide assistance to the bathroom
- B. Insert a straight catheter
- C. Increase fluids
- D. Perform a bladder scan
Correct answer: D
Rationale: Performing a bladder scan is the first step to assess bladder retention before any further interventions.
5. Selye's stress theory explains that a person stressed for long periods of time will:
- A. Face exhaustion and be more susceptible to illnesses.
- B. Become fatigued and become stronger.
- C. Become more assertive.
- D. Safety needs.
Correct answer: A
Rationale: Selye's stress theory posits that individuals experiencing prolonged stress are likely to face exhaustion and become more susceptible to illnesses. This is because the body's response to chronic stress can lead to physical and psychological depletion, increasing the risk of health problems. Choice B is incorrect as becoming stronger is not a typical outcome of prolonged stress according to Selye's theory. Choice C, becoming more assertive, is not directly related to the physical implications of chronic stress. Choice D, safety needs, is unrelated to Selye's stress theory and does not reflect the expected outcomes of prolonged stress.
