A nurse on a telemetry unit is assessing a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min and the PR interval is 0.24 seconds. The nurse should interpret this finding as which of the following cardiac rhythms?

1. Answer and explanation.

The correct answer is choice A. Increased Hct.

Hct stands for hematocrit, which is the percentage of red blood cells (RBCs) in the blood.

A client who received 2 units of packed RBCs should have an increased Hct because they have more RBCs in their blood volume. The normal range for Hct is 38% to 50% for males and 36% to 44% for females.

Choice B is wrong because decreased Hgb means decreased hemoglobin, which is the protein that carries oxygen in the RBCs.

A client who received 2 units of packed RBCs should have an increased Hgb because they have more hemoglobin in their blood. The normal range for Hgb is 13.5 to 17.5 g/dL for males and 12 to 15.5 g/dL for females.

Choice C is wrong because increased platelets means increased thrombocytes, which are the cells that help with blood clotting.

A client who received 2 units of packed RBCs should not have an increased platelet count because they did not receive platelets in the transfusion. The normal range for platelets is 150,000 to 400,000/mm^3.

Choice D is wrong because decreased WBC count means decreased leukocytes, which are the cells that fight infection and inflammation.

A client who received 2 units of packed RBCs should not have a decreased WBC count because they did not receive WBCs in the transfusion. The normal range for WBC count is 4,500 to 11,000/mm^3.

Choice A reason

Weight loss is not the correct answer: Weight loss is not a common side effect of simvastatin. In fact, weight loss is generally not associated with statin use. If the client experiences significant, unintentional weight loss, it may indicate another underlying issue that should be reported to the provider.

Choice B reason:

Muscle weakness is the correct answer. The nurse should instruct the client to monitor and report any muscle weakness to the healthcare provider when taking simvastatin. Simvastatin is a statin medication used to lower cholesterol levels in the blood. While statins are generally well-tolerated, they can occasionally cause muscle-related side effects, including muscle weakness or pain.

Rhabdomyolysis, a severe condition characterized by the breakdown of muscle fibres, is a rare but serious side effect of statin use. Muscle weakness may be an early sign of this condition. Therefore, if the client experiences any unexplained or persistent muscle weakness while taking simvastatin, it should be reported to the healthcare provider immediately.

Choice C reason

Fever is not the correct answer: Fever is not a common side effect of simvastatin. If the client develops a fever while taking simvastatin, it is more likely to be related to another condition and should be reported to the provider for further evaluation.

Choice D reason:

Edema is the correct answer: Edema (swelling) is not a common side effect of simvastatin. If the client experiences significant edema, especially in the extremities, it may indicate another underlying issue that should be reported to the provider.
