When testing visual fields, the nurse is assessing which of the following parts of vision?
- A. Peripheral vision
- B. Distance vision
- C. Near vision
- D. Central vision
Correct Answer: A
Rationale: The correct answer is A: Peripheral vision. When testing visual fields, the nurse evaluates the ability to see objects outside the direct line of sight, which is indicative of peripheral vision. Peripheral vision helps detect objects and movement in the side vision. Distance vision (B) refers to the ability to see clearly at a distance, while near vision (C) pertains to close-up vision. Central vision (D) is essential for focusing on details and seeing straight ahead. Therefore, A is the correct choice as it specifically pertains to the assessment of visual fields.

An adult has been treated for pulmonary tuberculosis and is being discharged home with his wife and two young children. His wife asks how TB is passed from one person to another so she can prevent anyone from catching it. How should the nurse respond?
- A. You should wear gloves when handling his linen and bedding
- B. You should keep the windows and doors closed so as not to spread the droplets
- C. He must be careful to cough into a handkerchief that is washed in hot water or discarded
- D. Make sure to boil all water before drinking or using it
Correct Answer: C
Rationale: Rationale:
Step 1: Coughing is the primary way TB bacteria are spread.
Step 2: By coughing into a handkerchief or tissue, the TB bacteria are contained.
Step 3: Washing the handkerchief in hot water or discarding it prevents the bacteria from spreading.
Step 4: This method reduces the risk of infecting family members.
Summary of Incorrect Choices:
A: Wearing gloves does not prevent airborne transmission of TB.
B: Keeping windows closed can increase the concentration of bacteria in the air.
D: Boiling water is not necessary to prevent TB transmission.
A nurse is caring for a patient with a nursing diagnosis of Constipation related to slowed gastrointestinal motility secondary to pain medications. Which outcome is most appropriate for the nurse to include in the plan of care?
- A. Patient will have one soft, formed bowel movement by end of shift.
- B. Patient will walk unassisted to bathroom by the end of shift.
- C. Patient will be offered laxatives or stool softeners this shift.
- D. Patient will not take any pain medications this shift.
Correct Answer: A
Rationale: The correct answer is A. The most appropriate outcome for the nurse to include in the plan of care is for the patient to have one soft, formed bowel movement by the end of the shift. This outcome directly addresses the nursing diagnosis of Constipation related to slowed gastrointestinal motility secondary to pain medications. By aiming for a soft, formed bowel movement, the nurse is working towards alleviating the constipation issue caused by the pain medications. This outcome is specific, measurable, achievable, relevant, and time-bound (SMART), making it an appropriate goal for the patient's care plan.
Choice B is incorrect because walking unassisted to the bathroom does not directly address the constipation issue. Choice C is incorrect as offering laxatives or stool softeners is a nursing intervention and not an outcome. Choice D is incorrect as withholding pain medications may not be in the best interest of the patient's overall care and does not directly target the constipation issue.
A client is diagnosed with megaloblastic anemia caused by vitamin B12 deficiency. The physician begins the client on cyanocobalamin (Betalin-12), 100mcg IM daily. Which substance influences Vitamin B12 absorption?
- A. Intrinsic factor
- B. Histamine
- C. Hydrochloric acid
- D. Liver enzyme
Correct Answer: A
Rationale: Rationale: Intrinsic factor is a glycoprotein produced by the stomach that is essential for the absorption of vitamin B12 in the ileum. Without intrinsic factor, vitamin B12 absorption is impaired, leading to megaloblastic anemia. Histamine and hydrochloric acid are not directly involved in vitamin B12 absorption. Liver enzymes are not implicated in the absorption process. Therefore, the correct answer is A.
A client receiving chemotherapy has a nursing diagnosis of Deficient diversional activity related to decreased energy. Which statement indicates an accurate understanding of appropriate ways to deal with this deficit?
- A. “I’ll play card games with my friends.”
- B. “I’ll take a long trip to visit my aunt.”
- C. “I’ll bowl with my team after discharge.”
- D. “I’ll eat lunch in a restaurant everyday.”
Correct Answer: C
Rationale: The correct answer is C because bowling with the team after discharge promotes social interaction and physical activity, addressing both the diversional activity deficit and the decreased energy. Playing card games (A) may not involve physical activity. Taking a long trip (B) may be overwhelming and tiring. Eating in a restaurant daily (D) does not address the need for meaningful activities or social interaction.
An adult has been diagnosed with some type of anemia. The results of his blood tests showed: decreased WBC, normal RBC, decreased HCT, decreased Hgb. Based on these data, which of the following nursing diagnosis should the nurse prioritize as the most important?
- A. Potential for infection
- B. Self care deficit
- C. Alteration in infection
- D. Fluid volume excess
Correct Answer: A
Rationale: The correct answer is A: Potential for infection. The decreased WBC count indicates reduced ability to fight off infections, making this the priority nursing diagnosis. Normal RBC count rules out anemia-related complications. Decreased HCT and Hgb indicate possible anemia but do not directly relate to infection risk. Choices B and C are not as critical as the potential for infection due to the significant impact on the individual's health and well-being. Choice D, fluid volume excess, is not directly related to the blood test results provided.
