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 A
Explanation
Choice A rationale
Veracity is the ethical principle of telling the truth and being honest with clients. By informing the client about the potential side effect of lightheadedness while also clarifying that the procedure should not affect their memory, the nurse is providing accurate and complete information. This honesty allows the client to make an informed decision and builds trust in the therapeutic relationship. The nurse is being truthful about the known risks and benefits of the treatment.
Choice B rationale
Beneficence is the ethical principle of doing good and acting in the best interest of the client. While the nurse's actions are ultimately intended to be beneficial, the specific act of providing truthful information is a demonstration of veracity. Beneficence would involve ensuring the treatment is appropriate and safe for the client, whereas veracity is the specific communication of the truth about that treatment's effects.
Choice C rationale
Autonomy is the ethical principle that respects a client's right to self-determination and to make their own decisions. While providing truthful information supports the client's ability to exercise their autonomy, the act of giving the information itself is an example of veracity. The nurse is upholding the client's autonomy by being truthful, but the action of being truthful is the core principle demonstrated.
Choice D rationale
Fidelity is the ethical principle of keeping promises and being loyal to the client. This involves maintaining professional commitments and a trusting relationship. While providing accurate information contributes to a trusting relationship, it is a direct fulfillment of the duty of veracity. Fidelity is more about honoring commitments and promises, which is a broader concept than simply telling the truth about a procedure's effects. *.
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. *.
