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
Looping the tubing so it is lower than the collection bag creates a dependent loop, which can cause urine to pool and create a backflow into the bladder. This stasis of urine provides a fertile environment for bacteria to multiply and ascend the urinary tract, significantly increasing the client's risk for a urinary tract infection. The bag should always be below the bladder.
Choice B rationale
Keeping the urinary bag at bladder level or higher when ambulating is a significant risk factor for urinary tract infections. This positioning allows for the backflow of urine from the collection bag into the bladder. The retrograde flow of urine can transport bacteria into the sterile bladder, leading to bacterial colonization and a subsequent infection.
Choice C rationale
Securing the catheter to the client's thigh is a crucial intervention for minimizing the risk of a UTI. It prevents movement and traction on the catheter at the urethral meatus. This minimizes urethral tissue irritation and micro-trauma, which can serve as entry points for bacteria. It also reduces tension on the catheter, preventing accidental dislodgement.
Choice D rationale
Disconnecting the tubing connections to obtain a urinary sample is a high-risk action for introducing microorganisms. Each disconnection breaks the closed, sterile system, allowing airborne bacteria or contaminants from the external environment to enter the catheter and tubing. This breach of sterility can lead to bacterial ascension into the bladder, causing a urinary tract infection. *.
