Correct Answer: D

Rationale: The correct answer is D. The desired action of oral contraceptives can be reduced when taken with tetracyclines like doxycycline. Therefore, patients on oral contraceptives should be advised to use a backup contraception method while taking doxycycline. Choice A is incorrect because nausea and vomiting are common adverse effects of doxycycline. Choice B is incorrect because doxycycline is not known for causing teratogenic effects. Choice C is incorrect because dairy products can interfere with the absorption of doxycycline, so they should be avoided when taking this medication.

Correct Answer: D

Rationale: The correct statements to include when teaching a client with stress incontinence about pelvic muscle exercises are that starting and stopping the urine stream involve using pelvic muscles and that tightening pelvic muscles for a slow count of 10 and then relaxing for a slow count of 10 can help strengthen them. It is essential to highlight that pelvic muscle exercises can be performed in various positions, including lying down, sitting up, and standing. This variety in positions helps engage the muscles effectively. Performing these exercises 15 times in each position can aid in strengthening the pelvic floor muscles. Consistent exercise over several weeks typically leads to improved control over urine leakage. Choice C is incorrect because pelvic muscle exercises can be performed in different positions and are not limited to sitting upright with feet on the floor.

Correct Answer: B

Rationale: Assessing blood pressure is the priority assessment when working with a population of African-American clients due to the high prevalence of hypertension in this group. African Americans have a higher risk of hypertension, which can lead to complications like end-stage renal disease. Monitoring blood pressure allows for the early detection and management of hypertension. While measuring height and weight, observing for signs of abuse, and asking about medications are important assessments, assessing blood pressure is crucial in this context to address the specific health needs of African-American clients.

Correct Answer: A

Rationale: The correct suction pressure for an adult client with a tracheostomy tube is typically between 80 to 120 mm Hg. Suction should be applied intermittently during catheter withdrawal to avoid damaging the airway. Assessing breath sounds before suctioning is important to ensure the procedure is necessary. Placing the client in a supine position before suctioning can compromise their airway; instead, the head of the bed should be elevated to facilitate proper drainage and reduce the risk of aspiration. Therefore, setting the suction pressure to 60 mm Hg is incorrect and would prompt the nurse to intervene and correct the procedure.

Correct Answer: B

Rationale: In a client who is vomiting, the loss of gastric fluid containing hydrochloric acid can lead to metabolic alkalosis. Metabolic alkalosis is caused by the loss of acids such as hydrochloric acid from the body. Therefore, in this scenario, the nurse should assess the client for metabolic alkalosis. Choices A, C, and D are incorrect because vomiting does not typically lead to metabolic acidosis, respiratory acidosis, or respiratory alkalosis.
