A male client has erectile dysfunction. Which systems should be assessed that could contribute to the erectile dysfunction?

Correct Answer: A

Rationale: Erectile dysfunction (ED) often stems from cardiovascular issues, like atherosclerosis or hypertension, which impair blood flow to the penis, a vascular process essential for erection. The integumentary system, while relevant to skin health, doesn't directly influence ED unless severe conditions affect genital tissue, which is rare. Endocrine disorders, such as diabetes or low testosterone, disrupt hormonal balance critical for libido and erectile function, making it a key area. The nervous system, including spinal cord injuries or neuropathy, affects nerve signals for arousal, another vital component. Cardiovascular assessment is prioritized because ED can signal underlying heart disease, with shared risk factors like smoking or high cholesterol, and its vascular basis often precedes overt cardiac symptoms, necessitating a thorough check of circulation and heart health to pinpoint or rule out this common cause.

Correct Answer: C

Rationale: In this question from the ATI Pharmacology book, the correct answer is option C) D. The rationale behind this is related to the FDA's categorization of drugs based on their potential risks during pregnancy. Category D includes drugs where human studies have shown fetal risks, but the potential benefits may outweigh the risks in certain situations. Option A) A is incorrect because Category A includes drugs that have been shown to be safe in pregnant women based on adequate and well-controlled studies. Option B) B is incorrect because Category B includes drugs that have not shown fetal risks in animal studies but have not been adequately studied in pregnant women. Option D) C is incorrect because Category C includes drugs for which animal studies have shown adverse effects on the fetus, but there are no adequate studies in pregnant women. Educationally, understanding the FDA pregnancy categories is crucial for healthcare professionals to make informed decisions when prescribing medications to pregnant women. It emphasizes the importance of weighing the potential risks and benefits of drug therapy during pregnancy to ensure the best possible outcomes for both the mother and the fetus.

Correct Answer: C

Rationale: In this scenario, the correct answer is C) Spend at least 20 minutes/day in the sunlight. The nurse should provide this information because exposure to sunlight is essential for the activation of vitamin D in the skin. Rickets, a condition characterized by soft or weak bones in children, is often caused by a deficiency in vitamin D. Sunlight exposure helps the body synthesize vitamin D, which is crucial for bone health. Option A) Avoid dairy products while taking vitamin D is incorrect because dairy products are a good source of calcium, which is important for bone health and can be beneficial for a child with rickets. Option B) Be sure to take brand name, not generic, vitamin D is incorrect as the effectiveness of generic versus brand name vitamins is generally the same, and what matters most is following the prescribed dosage. Option D) Take your vitamin D on an empty stomach is incorrect because vitamin D is a fat-soluble vitamin and is better absorbed when taken with a meal that contains fats. Educationally, this question highlights the importance of understanding the role of sunlight in the activation of vitamin D and how it relates to the treatment of conditions such as rickets. It also underscores the significance of providing accurate information to patients to ensure optimal treatment outcomes.

Correct Answer: C

Rationale: Fever and CO2 rise during surgery suggest malignant hyperthermia (MH). Dantrolene , a ryanodine receptor antagonist, halts MH by blocking calcium release. Acetaminophen reduces fever but not MH. Bromocriptine treats neuroleptic syndrome. Diazepam and Naproxen (E) are irrelevant. Dantrolene's specificity saves lives in this surgical emergency.

Correct Answer: A

Rationale: The correct answer is A) Cocaine. Cocaine is a stimulant drug that can cause symptoms such as agitation, paranoia, increased heart rate (tachycardia), elevated blood pressure, and tactile hallucinations like feeling bugs crawling on the skin (formication). These symptoms align with the presentation of the patient described in the scenario. Option B) Heroin is an opioid drug that typically causes symptoms like respiratory depression, sedation, pinpoint pupils, and euphoria. These symptoms do not match the presentation in the scenario. Option C) LSD is a hallucinogenic drug that can cause visual hallucinations, altered perceptions of reality, and changes in mood. While LSD can induce hallucinations, it is less likely to cause the specific symptoms described in the scenario. Option D) Methanol is a toxic alcohol that can lead to metabolic acidosis, visual disturbances, and other systemic effects. However, the symptoms of methanol poisoning differ from the stimulant effects seen with cocaine use. Educationally, understanding the effects of different classes of drugs is crucial for healthcare providers to recognize and manage drug intoxications effectively. Recognizing the specific signs and symptoms associated with various substances enables prompt and appropriate interventions in emergency situations. This case highlights the importance of a thorough understanding of pharmacology to provide optimal patient care.
