Insulin forces which of the following electrolytes out of the plasma and into the cells?
- A. Calcium
- B. Magnesium
- C. Phosphorus
- D. Potassium
Correct Answer: D
Rationale: Insulin forces potassium out of the plasma and into the cells, which can cause hypokalemia. This is because insulin enhances the activity of the sodium-potassium pump in cell membranes, promoting the movement of potassium from the extracellular fluid into the cells. Choices A, B, and C are incorrect as insulin does not directly influence the movement of calcium, magnesium, or phosphorus in the same manner as it does with potassium.

Which of the following healthcare providers can legally have access to all, or part, of a patient's medical record because they have a 'need to know'? Select one that does not apply.
- A. Student nurses caring for a particular patient
- B. Registered nurses when they are not caring for a particular patient
- C. The Vice President for nursing who is investigating a patient fall
- D. Licensed practical nurses caring for a particular patient
Correct Answer: B
Rationale: Student nurses, licensed practical nurses, the Vice President for nursing investigating a fall, and quality assurance nurses have a 'need to know' basis to access patient records. Registered nurses who are not directly involved in the care of a patient do not have a legitimate reason or 'need to know' to access that patient's medical records, making choice B the correct answer. The Vice President for nursing investigating a specific incident and licensed practical nurses directly involved in a patient's care have legitimate reasons to access the medical records, ensuring continuity and quality of care.
A nurse at a long-term care facility is planning a fall prevention program for the residents. Which of the following interventions should the nurse include?
- A. Apply vest restraints to residents who are confused
- B. Keep all four side rails up on beds at night
- C. Accompany residents over 85 years of age during ambulation
- D. Implement rounds every 2 hours during the day to offer toileting
Correct Answer: D
Rationale: The correct answer is to implement rounds every 2 hours during the day to offer toileting. This intervention helps prevent falls by addressing the common cause of unassisted mobility, which is the need to use the bathroom. Choice A is incorrect as restraints should not be the first choice for fall prevention due to the risk of injury and loss of independence. Choice B is incorrect because all side rails up can lead to entrapment and should only be used based on individualized assessments. Choice C may not be feasible for all residents over 85 years old and does not directly address the risk of falls.
What is idiopathic thrombocytopenia purpura?
- A. Highly similar to disseminated intravascular coagulation (DIC).
- B. Caused by the overproduction of platelets.
- C. A bleeding disorder that is characterized by too few platelets.
- D. Treated with immune system-boosting medications.
Correct Answer: C
Rationale: Idiopathic thrombocytopenic purpura is a bleeding disorder characterized by a low number of platelets in the blood. This condition is not highly similar to disseminated intravascular coagulation (DIC), which involves abnormal clotting throughout the body (coagulation), leading to depletion of platelets. Choice B is incorrect because idiopathic thrombocytopenic purpura is actually characterized by a decrease in platelet count, not an overproduction. While immune system-boosting medications may be used in some cases, the primary treatment for idiopathic thrombocytopenic purpura focuses on increasing platelet counts or managing symptoms.
Select a myth or falsehood relating to pain, pain management, and addiction.
- A. Addiction can be accurately predicted.
- B. Withdrawal, drug tolerance, and physical dependence do not indicate addiction.
- C. Pain medications should be avoided in patients with a substance abuse history.
- D. Addiction is signaled by deception and stockpiling by the client.
Correct Answer: A
Rationale: The correct answer is A because addiction cannot be accurately predicted. Choices B and C are incorrect. Withdrawal, drug tolerance, and physical dependence are not definitive signs of addiction, and pain medications can be used with patients who have a substance abuse history under careful monitoring. Choice D is incorrect because addiction is not solely signaled by deception and stockpiling; it is a complex condition with various behavioral, physical, and psychological aspects.
A patient's serum potassium level is 2.2 mEq/L. Which nursing action is the highest priority for this patient?
- A. Start oxygen at 2 L/min
- B. Initiate cardiac monitoring
- C. Initiate seizure precautions
- D. Keep the patient on bed rest
Correct Answer: B
Rationale: The correct answer is to initiate cardiac monitoring. Severe hypokalemia can lead to life-threatening arrhythmias, making cardiac monitoring the priority to detect and manage any cardiac complications. Starting oxygen, seizure precautions, or bed rest are not the immediate priority actions for severe hypokalemia.
