Correct Answer: B

Rationale: Digoxin is a medication commonly used in the treatment of congestive heart failure because it helps to improve cardiac output and reduce heart failure symptoms. One of the desired effects of digoxin is an increase in urinary output. This is because digoxin helps to improve cardiac function, which can lead to better circulation and increased kidney perfusion. As a result, the kidneys are better able to filter and excrete excess fluid, leading to increased urine output. Therefore, an increase in urinary output indicates that the digoxin is having a positive effect in managing the client's congestive heart failure. The other options, such as increased weight, improved appetite, and increased pedal edema, are not indicative of a desired effect of digoxin therapy.

Correct Answer: D

Rationale: When determining the existence of malpractice, intent is not considered as a factor. Malpractice typically involves unintentional actions or negligence rather than a deliberate intent to cause harm. The key factors that are usually considered in a malpractice case include duty (a legal obligation to provide a certain standard of care), causation (the link between the provider's actions and the patient's injury), and the existence of an injury resulting from the provider's actions or omissions. Intent does not play a direct role in malpractice cases, as they are focused on the standard of care provided by the healthcare professional and the harm caused as a result.

Correct Answer: A

Rationale: Attention deficit hyperactivity disorder (ADHD) is characterized by inattentiveness, overactivity, and impulsiveness. Individuals with ADHD may have difficulty paying attention, completing tasks, sitting still, or controlling their impulses. Mental retardation (now referred to as intellectual disability) is a separate condition characterized by limitations in intellectual functioning and adaptive behaviors. While individuals with ADHD may experience difficulties in school or work due to their symptoms, ADHD itself does not indicate mental retardation.

Correct Answer: B

Rationale: Record-keeping is not an optional task; it is a critical aspect of professional nursing practice. As a nurse, maintaining accurate and timely records is essential for providing quality care, ensuring legal and ethical standards are met, and promoting patient safety. Failure to keep thorough records can lead to serious consequences such as compromising patient care, violating regulations, and even facing legal consequences. Thus, record-keeping should be seen as a mandatory part of the professional duty of nurses rather than an optional task that can be done when circumstances allow.

Correct Answer: A

Rationale: The patient's presentation of sudden-onset, painless vision loss in the right eye, along with a cherry-red spot at the macula and attenuated retinal vessels, is classic for central retinal artery occlusion (CRAO). In CRAO, there is a sudden blockage of the central retinal artery, leading to ischemia of the retina. The cherry-red spot represents the preserved choroid blood flow against the ischemic retina. The attenuated retinal vessels are a result of decreased blood flow in the retinal circulation. This condition is considered an ophthalmic emergency and requires immediate evaluation and management to prevent permanent vision loss.
