Question 1 of 5
The nurse is assessing a client with suspected hypokalemia. Which finding supports this diagnosis?
Correct Answer: A
Rationale: Muscle weakness is a common sign of hypokalemia due to impaired muscle function.
Question 2 of 5
The nurse is obtaining a health history on the client with a possible left-sided varicocele. Which question is most important?
Correct Answer: C
Rationale: A. Varicoceles are not inherited. B. A varicocele does occur most frequently on the left side due to retrograde blood flow from the renal vein; however, a varicocele rarely produces symptoms. C. Asking about children is important because the most common cause of male infertility is a varicocele. Approximately 15% to 20% of the healthy, fertile male population is estimated to have varicoceles. However, 40% of infertile men may have them. D. A varicocele rarely produces any symptoms. It is usually diagnosed during physical examinations related to infertility. If symptoms do occur, pain and groin tenderness are the most common symptoms.
Question 3 of 5
The client, who had been prescribed sildenafil 2 weeks ago for erectile dysfunction, calls the clinic to report that nothing happens, despite taking sildenafil orally and waiting for his erection to develop. Which fact should the nurse consider before responding to the client?
Correct Answer: C
Rationale: A. In clinical trials, some improvement in erectile hardness and duration was reported by 70% of men taking sildenafil. B. Sildenafil should be taken orally. C. Sildenafil (Viagra) enhances the normal erectile response to sexual stimuli by promoting relaxation of arterial and trabecular smooth muscle. The resultant arterial dilation causes engorgement of sinusoidal spaces in the corpus cavernosum. In the absence of sexual stimuli, however, nothing will happen. D. A fatty meal delays absorption, and, as a result, plasma levels peak in 2 hours instead of an hour; it does not cause sildenafil to be ineffective.
Question 4 of 5
A client with a history of glaucoma is prescribed timolol eye drops. Which instruction should the nurse include?
