A patient receiving Morphine for postoperative pain relief displays slow, shallow breathing with a rate of 8 breaths/minute. The nurse recognizes this as a side effect called:

Miosis

Sedation

Respiratory depression

Euphoria

Answer and Explanation

The Correct Answer is C

Choice A reason: This is incorrect. Miosis is the constriction of the pupils, which can also be caused by morphine, but it is not a life-threatening side effect. Miosis occurs because morphine stimulates the parasympathetic nervous system, which controls the muscles that constrict the pupils¹.

Choice B reason: This is incorrect. Sedation is the state of being calm, relaxed, and sleepy, which can also be caused by morphine, but it is not a life-threatening side effect. Sedation occurs because morphine depresses the central nervous system, which reduces the activity of the brain and the body.

Choice C reason: This is correct. Respiratory depression is the slowing down of breathing, which can be a life-threatening side effect of morphine. Respiratory depression occurs because morphine depresses the respiratory center in the brainstem, which regulates the rate and depth of breathing. If the breathing becomes too slow or shallow, the patient may not get enough oxygen and may lose consciousness or die.

Choice D reason: This is incorrect. Euphoria is the feeling of intense happiness, pleasure, or wellbeing, which can also be caused by morphine, but it is not a life-threatening side effect. Euphoria occurs because morphine stimulates the reward system in the brain, which releases dopamine, a neurotransmitter that causes positive emotions.

Correct Answer is D

Explanation

Choice A reason: This is incorrect. Aspirin can be used to relieve headache, but that is not its main function in this context. Aspirin is prescribed to patients who have had a heart attack to reduce the risk of another one.

Choice B reason: This is incorrect. Aspirin can be used to reduce fever, but that is not its main function in this context. Aspirin is prescribed to patients who have had a heart attack to reduce the risk of another one.

Choice C reason: This is incorrect. Aspirin does not act as an antiviral. It has no effect on viral infections. Aspirin is prescribed to patients who have had a heart attack to reduce the risk of another one.

Choice D reason: This is correct. Aspirin prevents further clot formation by inhibiting the activity of platelets, which are blood cells that help form clots. Clots can block the blood flow to the heart and cause a heart attack. Aspirin reduces the chance of this happening by making the blood less sticky.

A. You may experience increased urination as the medication takes effect. B. Rise slowly from sitting or lying positions to reduce the risk of dizziness. C. Be sure to take this medication on an empty stomach. D. You can expect to experience weight gain due to fluid retention.

Correct Answer is B

Explanation

Choice A reason: This is incorrect. Lisinopril is an angiotensin converting enzyme (ACE) inhibitor that lowers blood pressure and reduces the workload of the heart. It does not have a diuretic effect, meaning it does not increase urination.
Choice B reason: This is correct. Lisinopril can cause orthostatic hypotension, which is a sudden drop in blood pressure when changing positions. This can lead to dizziness, fainting, or falls. To prevent this, the nurse should instruct the client to rise slowly from sitting or lying positions and to avoid sudden movements.
Choice C reason: This is incorrect. Lisinopril can be taken with or without food. Taking it on an empty stomach does not improve its effectiveness or reduce its side effects.
Choice D reason: This is incorrect. Lisinopril does not cause weight gain due to fluid retention. In fact, it can help reduce edema, which is swelling caused by excess fluid in the body.
