A nurse is teaching a client who has a new prescription for tetracycline.
Which of the following information should the nurse include in the teaching?
You should take this medication with milk.
You should take this medication at bedtime.
Light sensitivity is an adverse effect of this medication.
Constipation is an adverse effect of this medication.
The Correct Answer is C
Choice A rationale
Tetracycline binds to divalent and trivalent cations such as calcium, magnesium, and aluminum. Milk and dairy products are rich in calcium, so taking tetracycline with milk significantly reduces its absorption from the gastrointestinal tract, rendering the medication less effective. The drug should be taken on an empty stomach with a full glass of water.
Choice B rationale
Taking tetracycline at bedtime is not a recommended practice for this drug. Although some medications are taken at night to avoid side effects or promote sleep, tetracycline can cause gastroesophageal reflux or esophagitis, particularly when a person lies down soon after ingestion. It is important to remain upright for at least 30 minutes after taking the medication.
Choice C rationale
Photosensitivity is a well-documented adverse effect of tetracycline. The drug sensitizes the skin to ultraviolet light, leading to an exaggerated sunburn reaction. This is due to the drug's accumulation in the skin and its ability to absorb light energy. Clients must be advised to use sunscreen, wear protective clothing, and avoid prolonged sun exposure.
Choice D rationale
Tetracycline is known to cause gastrointestinal side effects, but diarrhea is far more common than constipation. This is often due to the disruption of the normal gut flora, which can lead to opportunistic infections like Clostridium difficile. While not exclusively causing diarrhea, constipation is not a typical adverse effect and should not be the primary teaching point. *.

Correct Answer is B
Explanation
Choice A rationale
Visual disturbances are a less common side effect of risperidone and are not typically considered a priority finding. While they can be a nuisance for the client, they do not pose an immediate threat to the client's life. Other side effects require more immediate attention and intervention from the healthcare provider.
Choice B rationale
Risperidone can cause cardiac side effects such as QT prolongation, which can lead to life-threatening arrhythmias like Torsades de pointes. An irregular pulse is a critical finding that could indicate an underlying cardiac issue and requires immediate evaluation. This is a priority finding for the nurse to report to the provider.
Choice C rationale
Constipation is a common side effect of risperidone due to its anticholinergic properties. While it can cause discomfort, it is not an immediate life-threatening condition. The nurse should address this by encouraging fluid and fiber intake and possibly discussing a stool softener with the provider, but it is not the highest priority.
Choice D rationale
Dry mouth is a common and relatively benign side effect of risperidone. While it can cause discomfort and increase the risk of dental caries, it is not an urgent or life-threatening condition. The nurse can advise the client on strategies to manage this symptom, such as using sugar-free candies or chewing gum. *.
Correct Answer is C
Explanation
Choice A rationale
This location, the second intercostal space at the right sternal border, corresponds to the aortic valve area. Auscultation here allows the nurse to assess the sounds produced by the aortic valve, which are distinct from the mitral valve sounds. These sounds are generated as blood is ejected from the left ventricle into the aorta during systole.
Choice B rationale
The second intercostal space at the left sternal border is the correct anatomical location for auscultating the pulmonic valve. The pulmonic valve separates the right ventricle from the pulmonary artery, and listening here allows the nurse to assess the sounds of blood flow into the pulmonary circulation.
Choice C rationale
The fifth intercostal space at the left midclavicular line is the point of maximal impulse (PMI), also known as the apical pulse, which is the anatomical location for the mitral valve. This is the optimal site for auscultating the S1 and S2 heart sounds, as well as any murmurs or abnormal sounds associated with the mitral valve's function.
Choice D rationale
This location, the fourth intercostal space at the left sternal border, is the anatomical location for the tricuspid valve. Auscultation in this area allows the nurse to assess the sounds generated by the tricuspid valve, which regulates blood flow between the right atrium and the right ventricle. *.
