A nurse in a provider’s office performs a fecal occult blood test with a positive result on a client.
Which of the following clients may have a false positive result?

A. A client who has a venous stasis ulcer.

A client who has peripheral hematomas.

A client who underwent a barium swallow study.

A client who takes an iron supplement.

Answer and Explanation

The Correct Answer is C

Correct answer: C

A. A client who has a venous stasis ulcer: This is less likely to cause a false positive result. While ulcers can bleed, the fecal occult blood test is designed to detect small amounts of blood in the stool, not necessarily blood from other sources like venous stasis ulcers.

B. A client who has peripheral hematomas: Peripheral hematomas are typically not related to the fecal occult blood test. They generally wouldn’t affect the results unless there was significant bleeding or if the hematomas were a result of an underlying bleeding disorder.

C. A client who underwent a barium swallow study: This is the most likely to cause a false positive result. Barium used in the study can sometimes appear as a false positive on the test due to its interference with the chemical reactions used to detect blood.

D. A client who takes an iron supplement: Iron supplements can actually cause a false negative result rather than a false positive because they may darken the stool and mask the presence of blood.

Correct Answer is B

Explanation

This means low sodium levels in the blood.

Sodium is an electrolyte that helps regulate fluid balance and nerve and muscle function.

Vomiting and diarrhea can cause dehydration and loss of sodium through fluids.

Normal sodium levels are between 135 to 145 millimole/Liter.

Choice A is wrong because hypermagnesemia means high magnesium levels in the blood.

Magnesium is another electrolyte that helps with nerve and muscle function, as well as blood pressure and blood sugar regulation.

Hypermagnesemia is rare and usually caused by kidney failure or excessive use of magnesium supplements or laxatives.

Normal magnesium levels are between 1.46 to 2.68 milligram/deciliter.

Choice C is wrong because hypocalcemia means low calcium levels in the blood.

Calcium is an electrolyte that helps with bone health, muscle contraction, blood clotting and nerve signaling.

Hypocalcemia can be caused by vitamin D deficiency, kidney disease, thyroid problems or certain medications.

Normal calcium levels are between 8.8 to 10.7 milligram/deciliter.

Choice D is wrong because hyperkalemia means high potassium levels in the blood.

Potassium is an electrolyte that helps with nerve and muscle function, especially the heart.

Hyperkalemia can be caused by kidney disease, diabetes, adrenal gland disorders or certain medications.

Normal potassium levels are between 3.6 to 5.5 millimole/Liter.

A. Devout practitioners of Buddhism prefer a ritual bath prior to burial. B. Devout practitioners of Islam prefer to have their heads turned toward Mecca at death. C. Devout practitioners of Judaism prefer to be buried 5 days after death. D. Devout practitioners of Hinduism prefer to be buried after death and not cremated.

Correct Answer is B

Explanation

The correct answer is choice B. Devout practitioners of Islam prefer to have their heads turned toward Mecca at death.

This is because Mecca is considered the holiest city in Islam and facing it is a sign of respect and devotion.

Choice A is wrong because devout practitioners of Buddhism prefer to be cremated rather than buried.

Cremation is seen as a way of releasing the soul from the body and preparing for rebirth.

Choice C is wrong because devout practitioners of Judaism prefer to be buried as soon as possible after death, usually within 24 hours.

This is based on the biblical commandment to bury the dead quickly and respect their dignity.

Choice D is wrong because devout practitioners of Hinduism prefer to be cremated after death and not buried.

Cremation is believed to help the soul detach from the body and achieve liberation.
