Which gauge IV cannula should the nurse choose when preparing to initiate a blood transfusion?
- A. 18
- B. 24
- C. 22
- D. 28
Correct Answer: A
Rationale: The correct choice is A: 18 gauge IV cannula for blood transfusion. Larger gauge allows for faster flow rate, crucial for transfusions to prevent clotting. 24, 22, and 28 gauge cannulas are too small for adequate blood flow, leading to potential complications like hemolysis or slowed infusion.

If Mr. Franco’s Right side is weak, What should be the most accurate analysis by the nurse?
- A. Expressive aphasia is prominent on clients with right sided weakness
- B. The affected lobe in the patient is the Right lobe
- C. The client will have problems in judging distance and proprioception
- D. Clients orientation to time and space will be much affected NEUROLOGIC NURSING Situation: A computer analyst, Mr. Ricardo J. Santos, 25 was brought to the hospital for diagnostic workup after he had experienced seizure in his office.
Correct Answer: B
Rationale: The correct answer is B because the right side weakness indicates a lesion in the left hemisphere of the brain. The brain's motor functions are contralaterally controlled, meaning the left hemisphere controls the right side of the body. Therefore, a right-sided weakness suggests a lesion in the left hemisphere. The other choices are incorrect because expressive aphasia is associated with left hemisphere lesions, judgment of distance and proprioception are more related to parietal lobe lesions, and orientation to time and space is not directly linked to right-sided weakness.
Decreasing level of consciousness is a symptom of which of the following physiological phenomena?
- A. Increased ICP
- B. Parasympathetic response
- C. Sympathetic response
- D. Increased cerebral blood flow
Correct Answer: A
Rationale: The correct answer is A: Increased ICP. Decreasing level of consciousness is a classic sign of increased intracranial pressure (ICP) due to the compression of the brain. As ICP rises, it impairs cerebral perfusion leading to altered mental status. Parasympathetic response (B) and sympathetic response (C) are related to autonomic nervous system functions, not consciousness. Increased cerebral blood flow (D) might lead to conditions like hyperemia but does not directly cause a decreased level of consciousness.
A client undergoes a biopsy of a suspicious lesion. The biopsy report classifies the lesion according to the TNM staging system as follows: TIS, NO, MO. What does this classification mean?
- A. No evidence of primary tumor, no abnormal regional lymph nodes, and no evidence of distant metastasis
- B. Carcinoma is situ, no abnormal regional lymph nodes, and no evidence of distant metastasis
- C. Can’t assess tumor or regional lymph nodes and no evidence of metastasis
- D. Carcinoma in situ, no demonstrable metastasis of the regional lymph nodes, and ascending degrees of distant metastasis
Correct Answer: B
Rationale: Step 1: TIS stands for carcinoma in situ, which means cancer cells are present only in the layer of cells where they first developed.
Step 2: N0 indicates no abnormal regional lymph nodes are involved.
Step 3: M0 signifies no evidence of distant metastasis.
Therefore, the correct answer is B because it accurately interprets the TNM staging system for the biopsy report.
Summary:
A: Incorrect - TIS indicates carcinoma in situ, not no evidence of primary tumor.
C: Incorrect - TIS already assesses tumor presence, ruling out this option.
D: Incorrect - TIS is not about ascending degrees of distant metastasis.
A narcotic analgesic is ordered for postoperative pain. Why are narcotics given in low doses to the laryngectomy patient?
- A. They depress the respiratory rate and cough reflex.
- B. They increase respiratory tract secretions.
- C. They have a tendency to cause stomal edema.
- D. They can cause addiction.
Correct Answer: A
Rationale: The correct answer is A because narcotics in high doses can depress the respiratory rate and cough reflex, which can be especially dangerous for a laryngectomy patient due to the risk of airway compromise. Low doses can provide pain relief without significant respiratory depression. Choices B and C are incorrect because narcotics typically do not increase respiratory tract secretions or cause stomal edema. Choice D is incorrect because while narcotics can potentially cause addiction, this is not the primary reason for giving low doses to laryngectomy patients.
Which statement by a nurse indicates a good understanding about the differences between data validation and data interpretation?
- A. “Data interpretation occurs before data validation.”
- B. “Validation involves looking for patterns in professional standards.”
- C. “Validation involves comparing data with other sources for accuracy.”
- D. “Data interpretation involves discovering patterns in professional standards.”
Correct Answer: C
Rationale: The correct answer is C because data validation involves comparing data with other sources to ensure accuracy. This step ensures that the data is reliable and error-free. Option A is incorrect as data validation typically comes after data collection and cleaning, which precede data interpretation. Option B is incorrect as validation does not specifically focus on professional standards but rather on accuracy and consistency. Option D is incorrect as data interpretation involves analyzing and deriving insights from the validated data, not looking for patterns in professional standards.
