The nurse collects data for a client who is diagnosed with mitral stenosis with a murmur. In which position does the nurse place the client to auscultate the documented murmur?

Left lateral

Right lateral

Prone

Supine

Answer and Explanation

The Correct Answer is A

A. Left lateral: Placing the client in the left lateral decubitus position brings the heart closer to the chest wall, especially the mitral valve. This position enhances the nurse’s ability to hear low-pitched diastolic murmurs like those associated with mitral stenosis.
B. Right lateral: This position does not improve the ability to hear mitral valve sounds. It moves the heart further from the chest wall and is not used for cardiac auscultation purposes.
C. Prone: A prone position is not used for heart assessments and may interfere with effective auscultation. It compresses the chest and limits access to key valve areas.
D. Supine: While commonly used for initial heart assessments, it may not be ideal for detecting low-frequency murmurs. Certain murmurs become more audible when the client is in a specific position, such as the left lateral for mitral stenosis.

Correct Answer is B

Explanation

A. Quality of the pulse: Pulse quality may indicate the presence of a rhythm, but it cannot confirm the presence of a pacemaker. A strong or weak pulse can occur in many conditions and is not a reliable pacemaker indicator.
B. "Spike" on the rhythm strip: Pacemakers produce a visible electrical “spike” on an ECG or rhythm strip, which precedes the QRS complex (or P wave in atrial pacing)or both (dual-chamber pacing). This spike confirms that the electrical impulse is generated by a pacemaker.
C. Scar on the chest: A scar may suggest prior pacemaker placement, but it is not definitive. Scars could be from other procedures or surgeries and do not confirm current pacemaker function.
D. Vibration under the skin: Pacemakers do not vibrate and typically cannot be felt moving under the skin. This is not a feature of the device and would not help identify its presence.

A. The spleen is lymphoid tissue in the upper chest that contains stem cells. B. The spleen assists with blood clotting. C. The spleen is a large lymph node and takes waste debris away. D. The spleen is a lymphatic structure and assists with phagocytosis

Correct Answer is D

Explanation

A. The spleen is lymphoid tissue in the upper chest that contains stem cells: The spleen is located in the left upper abdomen, not the chest, and it does not house hematopoietic stem cells. While it is lymphoid tissue, it does not primarily contain stem cells; stem cells are mainly found in the bone marrow.
B. The spleen assists with blood clotting: While the spleen stores platelets, its primary function is not clotting. It plays a secondary role in hemostasis but is more essential for filtering blood and immune responses.
C. The spleen is a large lymph node and takes waste debris away: The spleen is not a lymph node, although both are part of the lymphatic system. Lymph nodes filter lymph fluid, while the spleen filters blood. While the spleen does remove waste debris (through phagocytosis), it's not accurate to describe it as a large lymph node.
D. The spleen is a lymphatic structure and assists with phagocytosis: The spleen plays a critical role in immune defense by filtering blood, removing pathogens, and facilitating phagocytosis of old or damaged cells. Preserving it reduces the risk of overwhelming infections.
