Immediately after log-rolling a client to a lateral position, which intervention should the practical nurse (PN) implement?

Choice A rationale:

The combination of trimethoprim and sulfamethoxazole has a synergistic effect, which means that the two drugs work together to inhibit bacterial growth more effectively than either drug alone. This combination is commonly used to treat urinary tract infections (UTIs) caused by susceptible bacteria.

Choice B rationale:

The combination of trimethoprim and sulfamethoxazole does not have an additive effect that reduces the dosage and frequency of administration of each drug. Instead, it is prescribed as a fixed combination with specific dosages of each drug.

Choice C rationale:

The combination of trimethoprim and sulfamethoxazole does not have an antagonistic effect that prevents the development of resistance to either drug. In fact, the combination is chosen because it covers a broader spectrum of bacteria and reduces the likelihood of resistance development.

Choice D rationale:

The combination of trimethoprim and sulfamethoxazole does not have a selective effect that targets only the bacteria causing the UTI and spares the normal flora. It affects a wide range of bacteria, including both pathogenic and normal flora.

Choice A rationale:

Sinus tachycardia may occur in response to various stressors or physiological conditions but is not directly related to anorexia nervosa or severe malnutrition. It is not the primary pathological process resulting from this condition.

Choice B rationale:

Menstrual cramps are not a pathological process but rather a symptom that may result from hormonal changes or other factors. While amenorrhea (absence of menstrual periods) is a common feature of anorexia nervosa, menstrual cramps are not a primary concern in this context.

Choice C rationale:

Hypertension is not typically associated with anorexia nervosa or severe malnutrition. In fact, individuals with anorexia nervosa often experience hypotension (low blood pressure) due to dehydration and nutritional deficiencies.

Choice D rationale:

Amenorrhea is the primary pathological process resulting from the adolescent's consistent maladaptive behavior of anorexia nervosa. Severe malnutrition and low body weight can disrupt the normal menstrual cycle and lead to amenorrhea. This is a significant concern for individuals with anorexia nervosa and can have long-term health implications.
