A nurse is reinforcing discharge instructions with the parents of an infant who has been prescribed home oxygen and pulse oximetry monitoring.
Which statement by the parents suggests that further instruction is needed?
“The pulse oximeter may not be accurate during periods of excessive movement.”
“We will inform the doctor if the pulse oximeter consistently reads 100%.”
“The probe of the pulse oximeter can be attached to a finger or a toe.”
“We will move the probe of the pulse oximeter every 24 hours.”
The Correct Answer is B
Choice A rationale:
The statement “The pulse oximeter may not be accurate during periods of excessive movement” is correct. Pulse oximeters measure the amount of oxygen in the blood by shining light through the skin, and movement can cause the light to scatter, leading to inaccurate readings.
Choice B rationale:
The statement “We will inform the doctor if the pulse oximeter consistently reads 100%” indicates further instruction is needed. A pulse oximeter reading of 100% is not necessarily a cause for concern. It simply means that the hemoglobin is fully saturated with oxygen. However, if the oxygen level is consistently at 100%, it could indicate that the oxygen flow is too high and needs to be adjusted. It’s important to follow the healthcare provider’s instructions regarding the desired oxygen saturation level for the infant.
Choice C rationale:
The statement “The probe of the pulse oximeter can be attached to a finger or a toe” is correct. The probe of a pulse oximeter can indeed be attached to a finger, toe, or even an earlobe. The important thing is that it’s attached to a part of the body with good blood flow. Choice D rationale:
The statement “We will move the probe of the pulse oximeter every 24 hours” is correct. It’s important to move the probe periodically to prevent skin damage, such as pressure sores or burns, especially in infants who have delicate skin.

Correct Answer is ["A","B","C"]
Explanation
Choice A rationale:
Spinach is one of the most nutrient-dense vegetables. Just 1 cup (190 grams) of frozen spinach packs 12% of the DV for potassium. It’s also loaded with other nutrients. The same serving of frozen spinach contains 127% of the DV for vitamin A, 857% for vitamin K, 58% for folate, and 37% for magnesium.
Choice B rationale:
Potatoes are a staple food and are high in potassium. They are a versatile and filling food that can be included in a variety of dishes. Potatoes are also a good source of vitamin C and dietary fiber.
Choice C rationale:
Bananas are known as potassium-rich foods. A medium banana contains around 9% of the DV for this mineral. Most people consider it the go-to food to increase their potassium intake. However, bananas are not the only good source of potassium.
Choice D rationale:
Apples are a healthy choice and provide some potassium, but they are not as high in potassium as the other choices. Therefore, while apples are a good part of a balanced diet, they would not be the first recommendation for someone needing to increase their potassium intake.
Correct Answer is ["A","D","E"]
Explanation
Choice A rationale:
Antinuclear antibody (ANA) titer is a blood test that detects the presence of antinuclear antibodies, which are autoantibodies that target the body's own tissues. These antibodies are often present in people with autoimmune diseases, including rheumatoid arthritis.
While a positive ANA test does not definitively diagnose rheumatoid arthritis, it can support a diagnosis when considered alongside other clinical findings and laboratory tests.
Choice B rationale:
Blood urea nitrogen (BUN) is a blood test that measures the amount of urea nitrogen in the blood. Urea nitrogen is a waste product that is produced when the body breaks down proteins.
BUN levels can be elevated in people with kidney disease, dehydration, or certain other medical conditions. However, BUN is not specifically used to diagnose rheumatoid arthritis.
Choice C rationale:
Urinalysis is a test that examines the urine for various substances, including cells, bacteria, and chemicals.
It can be used to diagnose a variety of conditions, including urinary tract infections, kidney disease, and diabetes. However, urinalysis is not typically used to diagnose rheumatoid arthritis.
Choice D rationale:
Erythrocyte sedimentation rate (ESR) is a blood test that measures how quickly red blood cells settle at the bottom of a test tube.
A high ESR can indicate inflammation in the body.
ESR is often elevated in people with rheumatoid arthritis, as it is a marker of inflammation.
Choice E rationale:
White blood cell count (WBC) is a blood test that measures the number of white blood cells in the blood. White blood cells are part of the immune system and help fight infection.
A high WBC count can indicate an infection or inflammation.
WBC count can be elevated in people with rheumatoid arthritis, as it is a marker of inflammation.
