Question 1 of 5
The nurse recognizes that the major early problem for Mr. Gabatan will be:
Correct Answer: A
Rationale: The correct answer is A: Bladder control. This is the major early problem for Mr. Gabatan because urinary retention is a common complication post-surgery, especially for older males like him. Bladder control is essential for preventing urinary tract infections and maintaining overall health. Quadriceps setting (B) and client education (C) are important but not as critical early on. Use of aids for ambulation (D) is important but not the major early problem compared to bladder control in this case.
Question 2 of 5
Which of the following parts of neuron transmits impulses away from the cell body?
Correct Answer: C
Rationale: The correct answer is C: Axon. The axon is the part of the neuron that transmits impulses away from the cell body towards other neurons or target cells. It is coated with a myelin sheath, which helps speed up the transmission of impulses. Dendrites (A) receive signals from other neurons, the neurolemma (B) is the outermost layer of the myelin sheath, and the synapse (D) is the junction between two neurons where neurotransmitters are released. Therefore, the axon is the only part of the neuron specifically responsible for transmitting impulses away from the cell body.
Question 3 of 5
Which drug class is used to reduce symptoms of muscle weakness from myasthenia gravis?
Correct Answer: A
Rationale: The correct answer is A: Anticholinesterase drugs. These drugs increase acetylcholine levels at neuromuscular junctions, helping improve muscle strength in myasthenia gravis. Adrenergic drugs (B) and beta-blocker drugs (D) are not typically used to treat muscle weakness in myasthenia gravis. Anticholinergic drugs (C) can worsen symptoms by blocking acetylcholine receptors, making them an inappropriate choice for this condition.
Question 4 of 5
Which of the ff nursing interventions may reduce hemostasis and decrease the potential for thrombophlebitis for a client with a neurologic disorder?
Correct Answer: B
Rationale: The correct answer is B: Keep extremities at neutral position. This intervention promotes proper blood flow and reduces the risk of thrombophlebitis by preventing compression or restriction of blood vessels. Removing and reapplying elastic stockings (choice A) can disrupt circulation and increase the risk of thrombophlebitis. Changing the client's position (choice C) may not directly address hemostasis or thrombophlebitis. Using a flotation mattress (choice D) is not specifically focused on maintaining proper positioning of the extremities to promote circulation.
Question 5 of 5
The client is taking phenyton (Dilantin) for seizure control. A sample is drawn to determine the serum drug level, and the nurse reviews the results. Which of the following would indicate a therapeutic serum drug range?
Correct Answer: A
Rationale: The correct answer is A (5 to 10 mcg/ml) because this range is typically considered therapeutic for phenytoin (Dilantin) for seizure control. Levels below 5 mcg/ml may be subtherapeutic, leading to inadequate seizure control. Levels above 10 mcg/ml can increase the risk of toxicity. Choices B, C, and D are incorrect because they are outside the optimal therapeutic range, leading to either ineffective treatment (B, C) or an increased risk of adverse effects (D). Monitoring drug levels helps ensure the medication's effectiveness while minimizing side effects.
