1. A patient’s serum osmolality is 305 mOsm/kg. Which term describes this patient’s body fluid osmolality?
- A. Iso-osmolar
- B. Hypo-osmolar
- C. Hyperosmolar
- D. Isotonic
Correct answer: C
Rationale: The correct term to describe a patient with a serum osmolality of 305 mOsm/kg is 'hyperosmolar.' Normal osmolality ranges from 280 to 300 mOsm/kg. A patient with an osmolality above this range is considered hyperosmolar. Choice A ('Iso-osmolar') implies an equal osmolality, which is not the case in this scenario. Choice B ('Hypo-osmolar') suggests a lower osmolality, which is incorrect based on the provided serum osmolality value. Choice D ('Isotonic') refers to a solution having the same osmolality as another solution, not describing the specific scenario of this patient being above the normal range.
2. Which assessment is most important for the nurse to include in the daily plan of care for a client with a burned extremity?
- A. Distal pulse intensity
- B. Skin integrity
- C. Pain levels
- D. Range of motion
Correct answer: A
Rationale: The correct answer is A: Distal pulse intensity. Monitoring distal pulses is crucial to ensure that circulation to the extremity is not compromised. This assessment helps in detecting any signs of decreased circulation, which is vital in managing a burned extremity. While skin integrity (choice B), pain levels (choice C), and range of motion (choice D) are also important assessments, monitoring distal pulse intensity takes precedence as it directly reflects the perfusion status of the affected extremity in a burned client.
3. A nurse from the maternity unit is floated to the critical care unit because of staff shortage on the evening shift. Which client would be appropriate to assign to this nurse?
- A. A client with a Dopamine drip IV with vital signs monitored every 5 minutes
- B. A client with a myocardial infarction that is free from pain and dysrhythmias
- C. A client with a tracheotomy of 24 hours in some respiratory distress
- D. A client with a pacemaker inserted this morning with intermittent capture
Correct answer: B
Rationale: In this scenario, it is more appropriate to assign a stable client, such as the one with a myocardial infarction who is free from pain and dysrhythmias, to a nurse who lacks specialized critical care experience. This client's condition is relatively stable and does not require immediate critical interventions. Choices A, C, and D involve clients with more complex and critical conditions that would be better managed by a nurse with specialized critical care training. Choice A involves a client on a Dopamine drip with frequent vital sign monitoring, Choice C has a client with a tracheotomy in respiratory distress, and Choice D describes a client with a pacemaker experiencing intermittent capture, all of which require a higher level of critical care expertise.
4. Glimepiride (Amaryl) is prescribed for a client with diabetes mellitus. A healthcare provider reinforces instructions for the client and advises them to avoid which of the following while taking this medication?
- A. Alcohol
- B. Organ meats
- C. Whole-grain cereals
- D. Carbonated beverages
Correct answer: A
Rationale: Alcohol should be avoided when taking glimepiride (Amaryl) because it can cause a disulfiram-like reaction and enhance the hypoglycemic effects of the medication. Consuming alcohol with glimepiride can lead to symptoms such as flushing, palpitations, nausea, and vomiting. Therefore, it is crucial for individuals on glimepiride therapy to steer clear of alcohol to prevent adverse reactions and maintain optimal medication efficacy.
5. A client with a head injury is receiving mechanical ventilation. Which finding indicates to the nurse that the client may be experiencing increased intracranial pressure (ICP)?
- A. Widening pulse pressure
- B. Sudden drop in heart rate
- C. A decrease in urine output
- D. Elevated blood pressure and widening pulse pressure
Correct answer: D
Rationale: In a client with increased intracranial pressure (ICP), the body's compensatory mechanisms lead to an elevation in blood pressure and a widening pulse pressure. This occurs due to the body's attempt to maintain cerebral perfusion. Therefore, elevated blood pressure and widening pulse pressure are classic signs of increased ICP and necessitate immediate attention. Choices A, B, and C are incorrect because a widening pulse pressure, sudden drop in heart rate, or decreased urine output are not specific indicators of increased ICP.
