After 1 week of hospitalization, Mr. Gray develops hypokalemia. Which of the following is the most significant symptom of his disorder?

Correct Answer: C

Rationale: Muscle weakness is a hallmark symptom of hypokalemia. Hypokalemia refers to low levels of potassium in the blood, which can affect muscle function. The decreased potassium levels can lead to muscle weakness, cramping, and even paralysis. These symptoms can impact various muscle groups in the body, making muscle weakness the most significant symptom to monitor and address in patients with hypokalemia.

Correct Answer: C

Rationale: Primary nursing care units have been proven to be highly satisfying for both patients and nurses. This model promotes a consistent and continuous relationship between a patient and a primary nurse, leading to improved communication, personalized care, and overall satisfaction for both parties involved.

Correct Answer: D

Rationale: The correct sequence for assessing the abdomen is auscultation, percussion, and palpation. Auscultation allows the healthcare provider to listen for bowel sounds, followed by percussion to assess for areas of tenderness or abnormal distention, and finally palpation to feel for masses or organ enlargement. This sequence ensures a systematic and thorough assessment of the abdomen.

Correct Answer: C

Rationale: The absence of the pedal pulse may not be significant if the patient has poor peripheral circulation or if the healthcare provider is focused on other pulse points. The pedal pulse is often weaker and may not always be palpable due to various factors, making its absence less concerning in certain situations. However, the absence of other pulses like radial or femoral pulses may indicate more critical conditions and require immediate attention.

Correct Answer: A

Rationale: Depression is the most common psychogenic disorder among elderly individuals. It can manifest as persistent feelings of sadness, hopelessness, and loss of interest in activities that were once enjoyed. Elderly individuals may also experience changes in appetite, sleep disturbances, and difficulty concentrating. Detecting and addressing depression in the elderly is crucial for their overall well-being and quality of life.

Correct Answer: C

Rationale: The incorrect statement is that 'The patient should always feed himself.' Patients with dysphagia may require assistance with feeding due to difficulty in swallowing safely. It is essential to provide appropriate support and supervision during meal times to prevent complications such as aspiration or inadequate nutrition intake.

Correct Answer: B

Rationale: Vitamin C requirements are increased during infancy, childhood, and pregnancy due to growth and development. However, during young adulthood, the body generally requires a consistent amount of Vitamin C as it is not undergoing rapid growth or physiological changes that necessitate an increase in Vitamin C intake.

Correct Answer: B

Rationale: A positive guaiac test is used to detect the presence of occult (hidden) blood in the stool, suggesting bleeding from the gastrointestinal tract. It is a rapid screening test that can provide immediate information to the healthcare provider about possible gastrointestinal bleeding in patients presenting with symptoms such as nausea, vomiting, diarrhea, and severe abdominal pain.

Correct Answer: A

Rationale: Notifying the physician is necessary when the urine output is less than 30 ml/hour as it indicates impaired kidney function. Adequate urine output is essential for monitoring kidney function, and a urine output less than 30 ml/hour could suggest potential renal issues that require medical attention.
