A nurse is teaching a client who is obese about orlistat. The nurse should instruct the client to report which of the following findings as an adverse effect of the medication?

Dark-colored stools

Constipation

Nausea

Abdominal pain

Answer and Explanation

The Correct Answer is A

Choice A reason: Dark-colored stools are an adverse effect of orlistat, a medication that blocks the absorption of fat in the intestines. The unabsorbed fat can cause the stools to become oily, foul-smelling, and dark in color. This can indicate a serious condition called steatorrhea, which can lead to malnutrition and vitamin deficiencies.

Choice B reason: Constipation is not an adverse effect of orlistat. In fact, orlistat can cause the opposite problem of diarrhea, especially if the client consumes too much fat in their diet. Constipation may be caused by other factors, such as dehydration, lack of fiber, or medication side effects.

Choice C reason: Nausea is not an adverse effect of orlistat. Nausea may be a symptom of other conditions, such as gastritis, gastroenteritis, or pregnancy. Nausea may also be caused by other medications, such as antibiotics, opioids, or chemotherapy drugs.

Choice D reason: Abdominal pain is not an adverse effect of orlistat. Abdominal pain may be a sign of other conditions, such as appendicitis, gallstones, or kidney stones. Abdominal pain may also be caused by other medications, such as NSAIDs, steroids, or oral contraceptives.

Correct Answer is D

Explanation

Choice A reason: Mental alertness is not affected by the administration of hypertonic solutions. Hypertonic solutions are fluids that have a higher concentration of solutes than the blood. They draw water out of the cells and into the blood vessels, increasing the blood volume and osmolarity.

Choice B reason: Decreased pulse is not a result of administering hypertonic solutions too quickly. On the contrary, hypertonic solutions can increase the pulse rate as they increase the blood volume and pressure.

Choice C reason: Decreased blood pressure is not a consequence of administering hypertonic solutions too quickly. Hypertonic solutions can raise the blood pressure as they increase the blood volume and osmolarity.

Choice D reason: Fluid overload is the correct answer. Administering hypertonic solutions too quickly can cause fluid overload, which is a condition where the body has too much fluid in the blood vessels. This can lead to symptoms such as edema, dyspnea, crackles, and weight gain. Fluid overload can also cause heart failure, pulmonary edema, and cerebral edema.

A. Half-normal saline solution B. 10% dextrose in water C. 5% dextrose and half-normal saline solution D. Lactated Ringer's solution

Correct Answer is D

Explanation

Choice A reason: Half-normal saline solution is a hypotonic solution, which means it has a lower concentration of solutes than the blood plasma. It can cause fluid to shift from the blood vessels into the cells, leading to cellular swelling and edema.

Choice B reason: 10% dextrose in water is a hypertonic solution, which means it has a higher concentration of solutes than the blood plasma. It can cause fluid to shift from the cells into the blood vessels, leading to cellular shrinkage and dehydration.

Choice C reason: 5% dextrose and half-normal saline solution is a hypertonic solution, which has the same effects as choice B. The dextrose increases the osmolarity of the solution, while the half-normal saline provides some electrolytes.

Choice D reason: Lactated Ringer's solution is an isotonic solution, which means it has the same concentration of solutes as the blood plasma. It maintains fluid balance and provides electrolytes such as sodium, potassium, calcium, and lactate. It is commonly used for fluid resuscitation, dehydration, and acidosis.
