Which of the following BP changes alerts the nurse to increasing ICP, and should be reported immediately?
- A. Gradual increase
- B. Widening pulse pressure
- C. Rapid drop followed by gradual increase
- D. Rapid fluctuations
Correct Answer: B
Rationale: The correct answer is B, Widening pulse pressure. This indicates increasing intracranial pressure (ICP) as it signifies a significant difference between systolic and diastolic blood pressure. A widening pulse pressure is a key sign of impending herniation and requires immediate intervention.
A: Gradual increase does not provide a clear indication of acute changes in ICP.
C: Rapid drop followed by gradual increase may suggest other conditions and is not specific to increasing ICP.
D: Rapid fluctuations may occur in various scenarios and do not specifically point to increasing ICP.
In summary, a widening pulse pressure is the most critical and specific indicator of increasing ICP among the choices provided.

Which of the ff. statements would the nurse understand is true when assessing normal auditory acuity using the Rinne test?
- A. The patient perceives sound equally in both ears.
- B. Air conduction is heard longer than bone conduction in both ears.
- C. Bone conduction is heard longer than air conduction in both ears.
- D. The patient’s left ear will perceive the sound better than the right ear.
Correct Answer: B
Rationale: The correct answer is B because in a normal Rinne test, air conduction is heard longer than bone conduction in both ears. This is due to the fact that air conduction involves the transmission of sound waves through the external auditory canal, middle ear, and inner ear, which is more efficient than bone conduction where the sound waves are transmitted directly to the inner ear through the bones of the skull. Therefore, when the tuning fork is placed on the mastoid bone (bone conduction) and then moved next to the ear (air conduction), the sound should be heard longer through air conduction.
Choice A is incorrect because normal auditory acuity does not necessarily mean equal perception in both ears. Choice C is incorrect as bone conduction should be heard shorter than air conduction in a normal Rinne test. Choice D is incorrect as the test does not determine which ear perceives sound better, but rather the difference in duration between air and bone conduction.
Which scenario best illustrates the nurse using data validation when making a nursing clinical decision for a patient? The nurse determines to remove a wound dressing when the patient reveals the time
- A. of the last dressing change and notices old and new drainage. The nurse administers pain medicine due at 1700 at 1600 because the patient reports
- B. increased pain and the family wants something done. The nurse immediately asks the health care provider for an order of potassium when a
- C. patient reports leg cramps.
- D. The nurse elevates a leg cast when the patient reports decreased mobility.
Correct Answer: A
Rationale: The correct answer is A because it demonstrates data validation in making a nursing clinical decision. The nurse assesses the time of the last dressing change and compares it with the appearance of old and new drainage. This process ensures that the decision to remove the wound dressing is based on accurate and validated data, leading to appropriate patient care.
Choice B is incorrect because it does not involve data validation. The decision is driven by increased pain and family requests, without verifying the underlying cause.
Choice C is incorrect as it involves responding to a patient's reported symptom (leg cramps), but it does not involve data validation in making the clinical decision.
Choice D is incorrect as it relies solely on the patient's report of decreased mobility without further data validation.
Why should the nurse closely monitor a client to ensure that the venous access device remains in the vein during a transfusion?
- A. It minimizes the risk of phlebitis
- B. It minimizes the risk of circulatory overload
- C. It minimizes the risk of pulmonary
- D. It minimizes the risk of localized edema embolism
Correct Answer: B
Rationale: The correct answer is B: It minimizes the risk of circulatory overload. When a venous access device dislodges during a transfusion, there is a risk of the infusion going into the surrounding tissues instead of the vein, leading to circulatory overload. This can result in fluid overload and potentially lead to serious complications such as heart failure. Monitoring the device ensures that the medication is delivered safely and effectively into the bloodstream.
Choices A, C, and D are incorrect:
A: Monitoring the device does not directly minimize the risk of phlebitis, which is inflammation of the vein.
C: Monitoring the device does not directly minimize the risk of pulmonary complications, which are not typically associated with a dislodged venous access device.
D: Monitoring the device does not directly minimize the risk of localized edema embolism, which is a blockage caused by a blood clot, air bubble, or other material in a blood vessel.
A client receives a sealed radiation implant to treat cervical cancer. When caring for this client, the nurse should:
- A. Consider the client’s urine, feces, and vomitus to be highly radioactive
- B. Consider the client to be radioactive for 10 days after implant removal
- C. Allow soiled linens to remain in the room until after the client is discharged
- D. Maintain the client on complete bed rest with bathroom privileges only
Correct Answer: A
Rationale: The correct answer is A because bodily fluids and excretions (urine, feces, vomitus) can become contaminated with radiation from the implant. Therefore, they should be considered highly radioactive and handled appropriately.
Choice B is incorrect because the client may remain radioactive for a longer period than 10 days post-implant removal.
Choice C is incorrect because soiled linens should be handled according to radiation safety protocols and removed promptly.
Choice D is incorrect because bed rest is not necessary unless specifically indicated by the healthcare provider; the client should be encouraged to move around as tolerated to prevent complications.
The nurse is explaining the action of insulin to a newly diagnosed diabetic client. During the teaching, the nurse reviews the process of insulin secretion in the body. The nurse is correct when stating that insulin is secreted from the:
- A. adenohypohysis.
- B. alpha cells of the pancreas.
- C. beta cells of the pancreas.
- D. parafollicular cells of the thyroid.
Correct Answer: C
Rationale: Rationale:
1. Insulin is a hormone produced by beta cells of the pancreas.
2. Beta cells are responsible for monitoring blood glucose levels and secreting insulin in response to high glucose levels.
3. Insulin helps regulate blood glucose by facilitating glucose uptake into cells.
4. Adenohypophysis secretes other hormones, not insulin.
5. Alpha cells of the pancreas secrete glucagon, not insulin.
6. Parafollicular cells of the thyroid secrete calcitonin, not insulin.
Summary:
Choice C is correct because insulin is indeed secreted from the beta cells of the pancreas. Choices A, B, and D are incorrect as they do not secrete insulin or are related to other hormones.
