A nurse is reinforcing teaching with a client about collecting a stool specimen to check for occult blood. Which of the following statements by the client indicates an understanding of the teaching?
"Eating pasteurized dairy products will affect my test results."
"Having urine mixed in with the stool will not affect the results."
"I should avoid eating red meat for 3 days before my test."
"I should collect a specimen once each week for 4 weeks."
The Correct Answer is C
When collecting a stool specimen to check for occult blood, it is important to avoid certain foods that can affect the test results, such as red meat. Red meat can cause false-positive results due to the presence of heme, which can mimic the appearance of blood in the stool.
By avoiding red meat for at least three days before the test, the client can help ensure more accurate results. pasteurized dairy products do not have a direct impact on stool occult blood test results. However, it is important to note that certain medications, such as bismuth subsalicylate (found in Pepto-Bismol), can affect the test results.
The presence of urine in the stool sample can potentially dilute or mask the presence of blood, leading to false-negative results. It is important
Occult blood testing is typically done as a one-time test unless otherwise specified by a healthcare provider. Collecting a specimen once each week for four weeks is unnecessary unless specifically instructed by the healthcare provider.

Correct Answer is C
Explanation
A.While increasing dietary fiber can help with constipation, a common side effect of iron supplements, it does not directly improve the absorption of the medication
B.Berries and citrus fruits, on the other hand, are good sources of vitamin C, which can actually enhance iron absorption. Therefore, eliminating them from the diet would not be beneficial for improving iron absorption.
C.The recommendation the nurse should make to improve the absorption of the iron supplement (ferrous sulfate) is to avoid drinking milk with the medication. Calcium in milk can interfere with the absorption of iron, so it is best to separate the consumption of these two substances.
D.Green tea contains compounds called tannins, which can interfere with iron absorption. Therefore, it is not recommended to take iron supplements with green tea.
Correct Answer is D
Explanation
Waiting 1 minute between suctioning attempts allows the client to recover and ensures that the procedure is not overly invasive. It also helps to prevent the client from becoming hypoxic.
The distance that the nasopharyngeal catheter should be inserted varies from person to person and therefore 10 cm is not standard.
During nasopharyngeal suctioning, the nurse should apply suction intermittently while withdrawing the catheter, not during insertion. Applying suction during insertion can cause tissue damage and increase the risk of trauma.
The nurse should also apply intermittent suction for no longer than 15 seconds to prevent hypoxia and damage to the mucosal lining. Suctioning for an extended period can cause discomfort and harm to the client.
