When a fertilized egg implants itself outside of the womb, usually in one of the fallopian tubes can be diagnosed as?

Appeared in: NVS Staff Nurse - 2022

Explanation

The question describes the implantation of a fertilized egg outside the uterus, which is the definition of an ectopic pregnancy.
Ectopic pregnancy occurs when the blastocyst implants in a location other than the endometrial lining of the uterine cavity.
The most common site for an ectopic pregnancy is the fallopian tube, accounting for nearly 95% of cases.
Within the fallopian tube, the ampulla is the most frequent site of implantation (70%).
This condition is a serious medical issue and a leading cause of pregnancy-related mortality in the first trimester.

Option A: Hormonal imbalance is a potential risk factor or cause that can affect tubal motility, but it is not the diagnosis for an abnormally implanted pregnancy.
Option B: Intrauterine pregnancy is the term for a normal pregnancy, where the fertilized egg implants inside the uterus. This is the opposite of what is described in the question.
Option C: Fertilization is the biological process of the fusion of sperm and egg to form a zygote. It is an event, not a diagnosis of a pregnancy's location.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Diagnosis of Ectopic Pregnancy as background academic context rather than a clinical decision trigger.
Early diagnosis of ectopic pregnancy is critical to prevent rupture, which is a life-threatening emergency.
Nurses play a key role in assessing patients for the classic triad of symptoms: amenorrhea, abdominal pain, and vaginal bleeding.
A key nursing intervention for a suspected ruptured ectopic pregnancy is to monitor for signs of hypovolemic shock (tachycardia, hypotension, pallor, dizziness) and prepare for immediate surgical intervention.

How to Approach the Question

First, analyze the question stem to identify the core concept. The key phrase is "fertilized egg implants itself outside of the womb."
Recall the definitions of different types of pregnancies and related processes.
Evaluate each option against the definition provided in the question.
Option A, 'Hormonal imbalance,' is a cause, not the condition itself. Eliminate it.
Option B, 'Intrauterine pregnancy,' is implantation inside the womb, the opposite of the question. Eliminate it.
Option C, 'Fertilization,' is the process of conception, not implantation. Eliminate it.
