Kaplan NCLEX Question of The Day

1. One week ago, a client was involved in a motor vehicle crash (MVC) and was brought to the Emergency Department (ED). In the emergency department, the client received two stitches to the forehead and was sent home. Today, the client's spouse notes that the client 'acts like he is drunk' and cannot control his right foot and arm. The nurse will suspect?

A. Meningitis
B. Absence seizure
C. Subdural hematoma
D. Meniere's disease

Correct answer: C

Rationale: Yes! The nurse will suspect a subdural hematoma. In this case, the client's presentation of acting intoxicated and experiencing loss of motor control in the right foot and arm is indicative of an acute subdural hematoma. This condition can occur after a head injury with a slow venous bleed, where symptoms may not show until compensation mechanisms are overwhelmed. Meningitis (choice A) usually presents with fever, headache, and neck stiffness. Absence seizure (choice B) is characterized by brief periods of unconsciousness without convulsions. Meniere's disease (choice D) manifests with symptoms like vertigo, hearing loss, and tinnitus, which do not match the client's current symptoms.

2. Nurses should understand the chain of infection because it refers to:

A. the linkages involved in disease transmission.
B. the sequence required for transmission of disease.
C. the clustering of bacteria in a specific pattern.
D. increasing virulence patterns among microorganisms.

Correct answer: B

Rationale: The chain of infection refers to the sequence required for the transmission of disease, involving steps like the pathogen's presence, movement from a reservoir, and entry into a susceptible host. Understanding this sequence helps healthcare professionals, including nurses, in implementing effective infection control measures. Choices A, C, and D are incorrect because they do not accurately describe the concept of the chain of infection. Choice A is too broad and does not specifically address the sequential nature of disease transmission. Choice C focuses on bacterial clustering rather than the transmission process. Choice D mentions virulence patterns, which are not the primary focus of the chain of infection concept.

3. A client has been taking a drug (Drug A) that is highly metabolized by the cytochrome P-450 system. He has been on this medication for 6 months. At this time, he is started on a second medication (Drug B) that is an inducer of the cytochrome P-450 system. You should monitor this client for:

A. increased therapeutic effects of Drug A.
B. increased adverse effects of Drug B.
C. decreased therapeutic effects of Drug A.
D. decreased therapeutic effects of Drug B.

Correct answer: C

Rationale: When a client is taking a drug (Drug A) metabolized by the cytochrome P-450 system and is then started on another drug (Drug B) that induces this system, the metabolism of Drug A is increased. This results in decreased therapeutic effects of Drug A as it is broken down more rapidly. Monitoring is required to address potential reduced efficacy. The therapeutic effect of Drug A is diminished, not enhanced. Inducing the cytochrome P-450 system does not directly increase the adverse effects of Drug B. Although Drug B is an inducer, its therapeutic effects are not decreased as it is not metabolized faster.

4. A person who had a left CVA and right lower extremity hemiparesis is being instructed by a nurse to use a quad cane. Which of the following is the most appropriate gait sequence?

A. Place the cane in the patient's left upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
B. Place the cane in the patient's left upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.
C. Place the cane in the patient's right upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
D. Place the cane in the patient's right upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.

Correct answer: A

Rationale: The correct gait sequence for a person with left CVA and right lower extremity hemiparesis using a quad cane is to place the cane in the patient's strong upper extremity, which is the left upper extremity in this case. The correct sequence should be right lower extremity followed by left upper extremity, as this pattern mimics a normal gait pattern. Therefore, Choice A is the correct answer. Choices B, C, and D are incorrect because they do not follow the proper gait sequence for this specific patient's condition. The cane should be placed in the strong upper extremity, and the affected lower extremity should move first to provide stability and support, which is essential in this situation.

5. When administering intravenous electrolyte solution, which of the following precautions should the nurse take?

A. Infuse hypertonic solutions cautiously.
B. Mix no more than 60 mEq of potassium per liter of fluid.
C. Prevent infiltration of calcium, which causes tissue necrosis and sloughing.
D. Monitor the client's digitalis dosage for potential adjustments due to IV calcium administration.

Correct answer: C

Rationale: When administering intravenous electrolyte solutions, it is crucial to prevent infiltration of calcium to avoid tissue necrosis and sloughing. Hypertonic solutions should be infused cautiously (Choice A) to prevent adverse effects. The correct amount of potassium to be mixed in a liter of fluid is no more than 60 mEq, making Choice B incorrect. While monitoring the client's digitalis dosage for potential adjustments due to IV calcium administration is important, the statement suggesting an increased dosage is incorrect as IV calcium diminishes digitalis's action, making Choice D incorrect.
