1. 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.

2. After bronchoscopy, the nurse's priority is to check which of the following before feeding?

A. Gag reflex
B. Wearing off of anesthesia
C. Swallowing reflex
D. Peristalsis

Correct answer: A

Rationale: After a bronchoscopy procedure, the nurse's priority is to check the patient's gag reflex before allowing them to eat to prevent aspiration. The gag reflex helps protect the airway by triggering a cough or gag response if something touches the back of the throat. This is crucial to ensure that the patient can protect their airway and prevent food or fluids from entering the lungs, especially when the throat may be sensitive or compromised post-bronchoscopy. Checking for the wearing off of anesthesia, swallowing reflex, or peristalsis are important assessments but not the immediate priority before feeding in this context.

3. A nurse is providing teaching to an obese client who has gestational diabetes and is at 25 weeks of gestation. Which of the following statements made by the client indicates a need for further teaching?

A. This does not mean that my baby will have this disease.
B. This means that I will have diabetes for the rest of my life.
C. If I feel dizzy, I should drink six ounces of a non-diet soda.
D. Being obese might be one reason why I developed diabetes.

Correct answer: B

Rationale: The statement 'This means that I will have diabetes for the rest of my life' indicates a need for further teaching. Gestational diabetes often resolves after pregnancy, although it does indicate a higher risk for developing type 2 diabetes in the future. The other choices are correct or provide appropriate information: A) Understanding that gestational diabetes does not mean the baby will have the disease is accurate. C) Advising to drink non-diet soda if feeling dizzy is incorrect and potentially harmful due to the sugar content. D) Recognizing that obesity can be a risk factor for developing diabetes is a valid statement.

4. All of the following are instructions for proper foot care to be given to a client with peripheral vascular disease caused by diabetes. Which one is not?

A. Trim nails using a nail clipper
B. Apply cornstarch to the foot
C. Always check the temperature of the water before bathing
D. Use canvas shoes

Correct answer: A

Rationale: The correct answer is 'A', which says trim nails using a nail clipper. This is incorrect because patients with peripheral vascular disease, particularly those caused by diabetes, should not trim their nails themselves due to the risk of injury, infection, and poor wound healing. The other options, 'B', 'C', and 'D', are correct advice for diabetic foot care. Applying cornstarch can help keep the feet dry and prevent fungal infections. Checking the water temperature before bathing can prevent burns, as patients with peripheral vascular disease often have decreased sensation in their feet. Wearing canvas shoes can improve foot ventilation and reduce the risk of foot ulcers and infections.
