A nurse is reviewing a client’s cardiac rhythm strips and notes a constant P-R interval of 0.35 seconds.
Which of the following dysrhythmias is the client displaying?

Atrial fibrillation.

Complete heart block.

First-degree atrioventricular block.

Premature atrial complexes.

Answer and Explanation

The Correct Answer is C

This is because the PR interval is longer than normal, which indicates a delay in the conduction of electrical impulses from the atria to the ventricles through the AV node. A normal PR interval is 0.12 to 0.2 seconds, or 3 to 5 small squares on the EKG strip. In this case, the PR interval is 0.35 seconds, which is more than 5 small squares.

Choice A is wrong because atrial fibrillation is a type of arrhythmia where the atria beat irregularly and rapidly, producing chaotic and variable P waves and an irregular ventricular response.

There is no constant PR interval in atrial fibrillation.

Choice B is wrong because complete heart block is a type of arrhythmia where there is no conduction of electrical impulses from the atria to the ventricles, resulting in independent and dissociated atrial and ventricular rhythms.

There are no consistent P waves or PR intervals in complete heart block.

Choice D is wrong because premature atrial complexes are extra beats that originate from the atria and interrupt the normal sinus rhythm.

They produce abnormal P waves that are different from the sinus P waves, and may have a shorter or longer PR interval depending on the timing of the impulse.

However, they do not cause a constant prolongation of the PR interval.

Correct Answer is A

Explanation

The correct answer is choicea. Swelling of the face.

Choice A rationale:

Swelling of the face can be a sign of preeclampsia, a serious condition that requires immediate medical attention.Preeclampsia can lead to complications for both the mother and the baby if not managed properly.

Choice B rationale:

Urinary frequency is a common symptom during pregnancy due to hormonal changes and the growing uterus pressing on the bladder.It is generally not a cause for concern unless accompanied by other symptoms like pain or burning during urination.

Choice C rationale:

Faintness upon rising, also known as orthostatic hypotension, is common in pregnancy due to changes in blood circulation.It can often be managed by rising slowly and ensuring adequate hydration.

Choice D rationale:

Bleeding gums are common during pregnancy due to hormonal changes that increase blood flow to the gums, making them more sensitive and prone to bleeding.Good oral hygiene can help manage this symptom.

A. Elevated pain level. B. Increased drowsiness. C. Frequent swallowing. D. Diminished breath sounds.

Correct Answer is C

Explanation

This indicates that the child may be experiencing hemorrhage because they are trying to clear the blood from their throat. Frequent swallowing is one of the initial signs of bleeding immediately after tonsillectomy.
Choice A is wrong because elevated pain level is not a specific sign of hemorrhage. Pain is expected after a tonsillectomy and can be managed with medication and fluids.
Choice B is wrong because increased drowsiness is not a specific sign of hemorrhage. Drowsiness can be caused by anesthesia, medication, or dehydration.

Choice D is wrong because diminished breath sounds are not a specific sign of hemorrhage. Diminished breath sounds can be caused by respiratory infection, asthma, or bronchospasm.
Normal ranges for hemoglobin and hematocrit are 11.5 to 15.5 g/dL and 34 to 45% for children, respectively.
Normal ranges for platelet count are 150,000 to 450,000/mm3 for both children and adults. Normal ranges for plasma clotting variables depend on the specific test and method used.
