A nurse is providing teaching to a client who has heart failure and a new prescription for furosemide. Which of the following statements should the nurse make?
"Rise slowly when getting out of bed "
“Taking furosemide can cause you to be overhydrated."
"Eat foods that are high in sodium."
“Taking furosemide can cause your potassium levels to be high."
The Correct Answer is A
A. "Rise slowly when getting out of bed." Furosemide can lead to significant fluid and electrolyte loss, causing orthostatic hypotension. Clients may experience dizziness or lightheadedness when changing positions. Rising slowly helps prevent falls and promotes safety.
B. “Taking furosemide can cause you to be overhydrated." Furosemide is a potent diuretic that promotes fluid excretion, not retention. The risk of dehydration and electrolyte imbalance is much higher than overhydration. Monitoring intake and output is essential.
C. "Eat foods that are high in sodium." High sodium intake increases fluid retention, which can worsen heart failure symptoms. Furosemide is often prescribed to manage fluid overload, and sodium-rich foods would counteract its effects. A low-sodium diet is recommended.
D. “Taking furosemide can cause your potassium levels to be high." Furosemide increases the excretion of potassium through the kidneys, often leading to hypokalemia. Low potassium levels can result in muscle weakness or cardiac arrhythmias.

Correct Answer is D
Explanation
A. "I will plan to spend time tanning between 10 a.m. and 2 p.m." UV radiation from the sun is strongest between 10 a.m. and 4 p.m., and sun exposure during this time significantly increases the risk of skin cancer. Outdoor activity should be minimized during peak hours.
B. "I will use an indoor tanning bed instead of going outside." Indoor tanning beds expose users to intense UV radiation, which also increases the risk of skin cancer. They are not a safer alternative to natural sunlight and should be avoided.
C. "I will use sunblock with an SPF of 10 when I am outdoors." SPF 10 provides minimal protection and is not adequate for skin cancer prevention. The recommended SPF is 30 or higher, applied generously and re-applied regularly.
D. "I will apply sunscreen before and after swimming." Sunscreen should be applied 15 to 30 minutes before sun exposure and re-applied every 2 hours, especially after swimming or sweating. This statement shows an understanding of proper sun protection practices.
Correct Answer is B
Explanation
A. Premature atrial complexes. These are early electrical impulses originating in the atria that cause premature heartbeats, but they do not consistently lengthen the P-R interval. The P-R interval usually remains within normal limits unless another condition is present.
B. First-degree atrioventricular (AV) block. A constant P-R interval longer than 0.20 seconds (normal range: 0.12–0.20 seconds) is characteristic of a first-degree AV block. A P-R interval of 0.35 seconds indicates a prolonged conduction delay through the AV node, consistent with this dysrhythmia.
C. Complete heart block. In complete (third-degree) heart block, there is no consistent relationship between P waves and QRS complexes, and the P-R interval is not constant. This is not consistent with a stable, prolonged P-R interval.
D. Atrial fibrillation. Atrial fibrillation is marked by irregularly irregular rhythm and absent, unidentifiable P waves, not a consistent P-R interval. The atria are quivering, not contracting in a coordinated way.
