The nurse is instructing a client who has been prescribed tetracycline (Sumycin). What should the nurse advise this client to avoid while taking this medication?

Green leafy vegetables

Sunlight

Exercise

Foods high in tyramine

Answer and Explanation

The Correct Answer is B

A.Green leafy vegetables:

There is no specific recommendation to avoid green leafy vegetables while taking tetracycline. However, it’s generally advisable to take tetracycline on an empty stomach, as certain foods and supplements containing calcium, magnesium, aluminum, iron, or zinc can interfere with the absorption of tetracycline if consumed concurrently. Green leafy vegetables are not typically high in these minerals, so there is no need to avoid them specifically.

B. Sunlight:

Tetracycline antibiotics, including Sumycin, can increase the skin’s sensitivity to sunlight and UV radiation, leading to an increased risk of sunburn and photosensitivity reactions. Therefore, clients taking tetracycline should be advised to minimize sun exposure, wear protective clothing, and use sunscreen with a high sun protection factor (SPF) to reduce the risk of sunburn and skin damage.

C. Exercise:

There is no specific contraindication to exercise while taking tetracycline. In fact, regular exercise can promote overall health and well-being. However, it’s essential for clients to listen to their bodies and avoid strenuous exercise if they experience any adverse effects or symptoms while taking tetracycline or any other medication.

D. Foods high in tyramine:

Tetracycline antibiotics do not interact with tyramine-containing foods in the same way as certain other classes of antibiotics, such as monoamine oxidase inhibitors (MAOIs). Therefore, there is no specific need to avoid foods high in tyramine while taking tetracycline, as tyramine-related interactions are not typically associated with tetracycline use.

Correct Answer is C

Explanation

A. BP 98/62:

A blood pressure of 98/62 mmHg is within the normal range for an adult, although it's slightly lower than the average blood pressure. While monitoring blood pressure is important, this reading doesn't indicate a critical condition and doesn't require immediate intervention.

B. Urticaria:

Urticaria, also known as hives, is a skin rash characterized by raised, itchy welts. While it can be uncomfortable and may indicate an allergic reaction, it's not immediately life-threatening. However, it does warrant attention and further assessment.

C. Wheezing:

Wheezing is a high-pitched whistling sound that occurs during breathing and can indicate airway obstruction, such as in an allergic reaction or asthma exacerbation. Wheezing can be a sign of a severe allergic reaction or anaphylaxis, which requires immediate intervention to ensure the patient's airway remains open and to administer appropriate treatment.

D. Pulse rate 104/min:

A pulse rate of 104 beats per minute (bpm) is slightly elevated but within the normal range for an adult. While it's important to monitor heart rate, this finding alone doesn't indicate an immediate threat to the patient's life.

A. do not have to demonstrate effectiveness B. are determined to be safe before being placed on the market C. are checked for label accuracy D. are tested prior to marketing

Correct Answer is A

Explanation

Do not have to demonstrate effectiveness:

This statement is generally true under DSHEA regulations. Unlike pharmaceutical drugs, dietary supplements are not required to undergo rigorous testing to demonstrate their effectiveness in treating, preventing, or curing specific health conditions before they are marketed. However, manufacturers are prohibited from making unsubstantiated claims about the effectiveness of their products.

B. Are determined to be safe before being placed on the market:

Under DSHEA regulations, dietary supplement manufacturers are responsible for ensuring the safety of their products before they are marketed. However, unlike pharmaceutical drugs, dietary supplements do not undergo premarket approval by the Food and Drug Administration (FDA) to verify their safety and efficacy. Instead, manufacturers are required to notify the FDA of their intent to market a new dietary ingredient (NDI) and provide evidence of the ingredient’s safety.

C. Are checked for label accuracy:

The FDA regulates dietary supplements to ensure that their labels are accurate and truthful. However, the extent of label accuracy checking varies, and the FDA does not routinely test every dietary supplement product on the market. Instead, the FDA relies on postmarket surveillance, consumer complaints, and other mechanisms to identify and address inaccuracies or violations of labeling regulations.

D. Are tested prior to marketing:

Unlike pharmaceutical drugs, dietary supplements are not required to undergo premarket testing to demonstrate their safety or efficacy before they are marketed. While manufacturers are responsible for ensuring the safety of their products, there is no formal premarket testing requirement under DSHEA regulations.
