A brain abscess is a collection of pus within the substance of the brain and is caused by:
- A. Direct invasion of the brain
- B. Spread of infection by other organs
- C. Spread infection from nearby sites
- D. All of the above mechanisms
Correct Answer: D
Rationale: The correct answer is D because a brain abscess can be caused by direct invasion of the brain, spread of infection by other organs, and spread of infection from nearby sites. Direct invasion can occur from trauma or surgery, while infections from other organs like the lungs or heart can travel through the bloodstream to the brain. Infections from nearby sites such as the sinuses or ears can also spread to the brain. Therefore, all of these mechanisms can lead to the formation of a brain abscess. Choices A, B, and C alone do not encompass all the possible causes of a brain abscess, making D the correct comprehensive answer.

A client with serum glucose level of 618mg/dl is admitted to the facility. He’s awake and oriented, has hot dry skin, and has the following vital signs: temperature of 100.6F (38.1C), heart rate of 116 beats/min, and blood pressure of 108/70mHg. Based on these assessment findings, which nursing diagnosis take highest priority?
- A. Deficient volume related to osmotic diuresis
- B. Decreased cardiac output related to elevated heart rate
- C. Imbalanced nutrition: Less than body requirements related to insulin deficiency
- D. Ineffective thermoregulation related to dehydration
Correct Answer: D
Rationale: The correct answer is D, "Ineffective thermoregulation related to dehydration." The client's high serum glucose level of 618mg/dl indicates severe hyperglycemia, leading to dehydration. The client's hot, dry skin and elevated temperature can be signs of dehydration, impacting the body's ability to regulate temperature. Dehydration can also affect other vital signs, contributing to the elevated heart rate and low blood pressure. Addressing ineffective thermoregulation is crucial as it can lead to further complications.
Choices A, B, and C are not the highest priority because addressing dehydration and ineffective thermoregulation takes precedence due to the immediate risk of complications such as heatstroke or hypothermia. Deficient volume, decreased cardiac output, and imbalanced nutrition are important but not as urgent in this scenario.
A nurse is collecting data from a home care client. In addition to information about the client’s health status, what is another observation the nurse should make?
- A. Number of rooms in the house
- B. Safety of the immediate environment
- C. Frequency of home visits to be made
- D. Friendliness of the client and family
Correct Answer: B
Rationale: The correct answer is B: Safety of the immediate environment. This is crucial for the client's well-being and can impact their health. The nurse should assess for hazards like loose rugs, clutter, or slippery floors. This ensures a safe living environment for the client. The other choices (A, C, D) are not directly related to the client's immediate safety or well-being. The number of rooms in the house (A) is not as important as ensuring the safety of the environment. The frequency of home visits (C) can be planned later based on the initial assessment. The friendliness of the client and family (D) is important for building rapport but does not address the immediate safety concerns of the client.
The nurse is aware that in communicating with an elderly client, the nurse will
- A. Lean and shout at the ear of the client
- B. Use a low-pitched voice
- C. Open mouth wide while talking to the client
- D. Use a medium-pitched voice
Correct Answer: B
Rationale: The correct answer is B: Use a low-pitched voice. This is because elderly individuals may have age-related hearing loss, making it difficult for them to hear higher frequencies. Using a low-pitched voice can help ensure that the client can hear and understand the nurse clearly.
A: Leaning and shouting at the ear of the client may come across as aggressive and disrespectful.
C: Opening the mouth wide while talking is not necessary and may be seen as patronizing.
D: Using a medium-pitched voice may still be too difficult for the elderly client to hear clearly due to age-related hearing loss.
An adult had a total thyroidectomy. Which statement by the client demonstrates to the nurse an adequate understanding of long term care?
- A. “I will need to take replacement hormones for the rest of my life.”
- B. “ I should try to avoud stress and be alert for signs of recurrent hyperthyroidism.”
- C. “Thank goodness, this is over! I will never have to worry about throid problems again.”
- D. “ I should increase my caloric intake to replace what I lost during the surgery.”
Correct Answer: A
Rationale: The correct answer is A because after a total thyroidectomy, the client will no longer produce thyroid hormones, necessitating lifelong replacement therapy. This statement shows an understanding of the need for ongoing medication to maintain thyroid function. Choice B is incorrect as the client had a total thyroidectomy, so there is no risk of hyperthyroidism recurrence. Choice C is incorrect as the client will need ongoing care and monitoring for thyroid function. Choice D is incorrect as increasing caloric intake is not a necessary long-term care measure after a thyroidectomy.
A nurse finds Mr. Gabatan under the wreckage of the car. He is conscious, breathing satisfactorily, and lying on the back complaining of pain in the back and an inability to move his legs. The nurse should first:
- A. Leave Mr. Gabatan lying on his back with instructions to move and then go seek additional help
- B. Gently raise Mr. Gabatan to a sitting position to see if the pain either
- C. Roll Mr. Gabatan on his abdomen, place, a pad under his head, and cover him with any material available
- D. Gently lift Mr. Gavatan into a flat piece of lumber and using any available transportation, rush him to the nearest medical institution
Correct Answer: C
Rationale: The correct answer is C because in cases of suspected spinal injury, it is crucial to keep the spine immobilized to prevent further damage. Rolling Mr. Gabatan onto his abdomen helps protect his spine by maintaining alignment. Placing a pad under his head provides support and covering him with any material available helps maintain his body temperature. Moving him without proper spinal precautions (options A, B, D) could worsen his condition. Seeking additional help is important, but ensuring spinal immobilization comes first. Sitting him up or moving him onto a flat piece of lumber can exacerbate spinal injuries. Therefore, option C is the most appropriate initial action.
