Why is a pulse oximeter attached to Mr. Dizon's finger?
- A. To determine if the patient's hemoglobin level is low and if he requires a blood transfusion
- B. To check the level of the patient's tissue perfusion
- C. To measure the effectiveness of the patient's anti-hypertensive medications
- D. To detect oxygen saturation of arterial blood before symptoms of hypoxemia develop
Correct Answer: D
Rationale: A pulse oximeter is used to detect the oxygen saturation levels in arterial blood before the onset of hypoxemia symptoms. This device provides essential information about the effectiveness of oxygen transportation to the body's tissues. Choice A is incorrect because a pulse oximeter does not directly measure hemoglobin levels nor determine the need for a blood transfusion. Choice B is incorrect because a pulse oximeter is designed specifically to assess oxygen saturation, not tissue perfusion. Choice C is incorrect because a pulse oximeter is not used to measure the efficacy of anti-hypertensive medications, but rather to monitor oxygen levels in the blood.

When assessing older adult clients for malnutrition at an adult day care center, which risk factors should the nurse consider?
- A. Dental problems
- B. Depression
- C. Both A and B
- D. Ability to prepare meals
Correct Answer: C
Rationale: The correct answer is C: Both A and B. Dental problems and depression are both significant risk factors for malnutrition in older adults. Dental problems can lead to difficulty in chewing and swallowing, resulting in reduced food intake. On the other hand, depression can cause changes in appetite and decreased interest in eating, which can also contribute to malnutrition. Although the ability to prepare meals is important, it is not specifically identified as a risk factor for malnutrition within the context of this question. Therefore, choices A and B are the most appropriate answers.
Which food is a reliable source of B12 for a pregnant vegan client?
- A. Soybeans
- B. Algae
- C. Fortified soy milk
- D. Sea vegetables
Correct Answer: C
Rationale: Fortified soy milk is a reliable source of vitamin B12 for pregnant vegan clients as it is usually enriched with this vitamin. The other options, while nutritious, are not reliable sources of B12 for vegans. Soybeans may not provide enough B12, algae contains B12 analogs that the human body cannot utilize, and the B12 content in sea vegetables can fluctuate, potentially not providing the necessary daily intake.
During blood administration, what is essential for the nurse to do in order to carefully monitor for adverse reactions?
- A. Stay with the client for the first 15 minutes of blood administration
- B. Stay with the client for the entire period of blood administration
- C. Run the infusion at a faster rate during the first 15 minutes
- D. Inform the client to notify the staff immediately for any adverse reaction
Correct Answer: A
Rationale: In the context of blood administration, it's crucial for the nurse to stay with the client for the first 15 minutes. This is because most adverse reactions are likely to occur within this initial period. Monitoring the client closely during this time allows for immediate detection and response to any potential reactions. Choice B, staying with the client for the entire period of blood administration, is not typically feasible or necessary, although regular checks should be conducted. Running the infusion at a faster rate during the first 15 minutes (Choice C) is incorrect as this can actually increase the risk of adverse reactions. Informing the client to notify the staff immediately for any adverse reaction (Choice D) is an important practice, but it is not the most direct way for the nurse to monitor for adverse reactions.
Which individual would be at the greatest risk for deficiencies in water-soluble vitamins?
- A. An individual who regularly consumes fruits and vegetables.
- B. An individual with a high intake of dairy products.
- C. An individual who consumes a diet high in processed foods.
- D. An individual who frequently eats organ meats.
Correct Answer: C
Rationale: The correct answer is 'An individual who consumes a diet high in processed foods.' Processed foods are often deficient in water-soluble vitamins such as vitamin C and B vitamins, which can lead to deficiencies. On the other hand, fruits, vegetables, and organ meats are rich sources of these vitamins, so individuals who consume these regularly are less likely to develop deficiencies. While dairy products do contain some water-soluble vitamins, they are not depleted as quickly as they are in a diet high in processed foods, making a deficiency less likely.
What is the name of the record that shows all medications and treatments provided on a repeated basis?
- A. Nursing Health History and Assessment Worksheet
- B. Discharge Summary
- C. Nursing Kardex
- D. Medicine and Treatment Record
Correct Answer: D
Rationale: The 'Medicine and Treatment Record' is the document that maintains a comprehensive log of all medications and treatments provided on a routine basis. It does not refer to the 'Discharge Summary', which is a clinical report prepared by healthcare professionals at the end of a hospital stay or series of treatments. The 'Nursing Health History and Assessment Worksheet' is used to gather comprehensive data about the patient's health history and current health status, but it does not record ongoing treatment details. The 'Nursing Kardex' is a patient care information system used to quickly communicate patient needs, but it does not consistently record all medications and treatments provided.
