What spinal change occurring with pregnancy alters mobility?

A. Scoliosis.

B. Kyphosis.

C. Lordosis.

D. Ankylosing spondylitis.

Correct Answer: C
Rationale: The correct answer is 'Lordosis.' During pregnancy, the enlarging uterus places increased weight on the spine, causing an exaggerated inward curvature known as lordosis. This change alters mobility by shifting the center of gravity forward, leading to a compensatory change in posture. Scoliosis (choice A) is a sideways curvature of the spine, not typically associated with pregnancy. Kyphosis (choice B) is an exaggerated outward curvature of the spine, while ankylosing spondylitis (choice D) is a chronic inflammatory condition affecting the spine, neither of which are directly related to the spinal changes seen in pregnancy.

What is the term for the tendency of a drug to combine with its receptor?

• A. potency
• B. efficacy
• C. kinetics
• D. affinity

Correct Answer: affinity
Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (Choice A) is related to the dose of a drug needed to produce a specific effect. Efficacy (Choice B) refers to a drug's ability to generate the desired effect. Kinetics (Choice C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.

What information does the healthcare provider remember regarding do-not-resuscitate (DNR) orders in this scenario?

• A. That a DNR order may be written by a healthcare provider
• B. That everything possible must be done if the client stops breathing
• C. That medications only may be given to the client if the client stops breathing
• D. That life support measures will have to be implemented if the client stops breathing

Correct Answer: That a DNR order may be written by a healthcare provider
Rationale: In a situation where a client has no family members and the client's wife is mentally incompetent, the healthcare provider may write a DNR order if it is deemed medically certain that resuscitation would be futile. A DNR order is a medical directive that instructs healthcare providers not to perform CPR if a patient's heart stops or if the patient stops breathing. Option A is correct because a DNR order can indeed be issued by a healthcare provider under certain circumstances, as it is a medical decision. Options B, C, and D are incorrect as they do not accurately reflect the concept of DNR orders and the decision-making process involved in such situations.

Which of these would be an appropriate meal for a client with Celiac disease?

• A. egg noodles with cream sauce and broccoli, oat cookie, almond milk
• B. turkey sandwich with rye bread, carrots
• C. chicken and rice, apple, and tapioca pudding
• D. granola and dried apricots with cow’s milk

Correct Answer: chicken and rice, apple, and tapioca pudding
Rationale: For individuals with Celiac disease, it's crucial to avoid gluten-containing foods. Choice C, which includes chicken, rice, apple, and tapioca pudding, is the most suitable option as all these foods are naturally gluten-free. Rice, fruits, vegetables, meat, dairy, and tapioca are all safe gluten-free options. Oats can be gluten-free if specially labeled, but many are processed on shared equipment with wheat. Granola often contains oats that may have been exposed to gluten. Dried and prepackaged fruits may contain gluten additives. Rye is a wheat derivative, and cream sauces usually contain flour as a base, making choices A and B inappropriate for individuals with Celiac disease.

The nurse is teaching a client about erythema infectiosum. Which of the following factors is not correct?

• A. There is no rash.
• B. The disorder is uncommon in adults.
• C. There is no fever.
• D. There is sometimes a 'slapped face' appearance.

Correct Answer: The disorder is uncommon in adults.
Rationale: The correct answer is B: 'The disorder is uncommon in adults.' Erythema infectiosum, also known as Fifth's disease, is more common in children than in adults. It typically presents with a rash on the face that gives a 'slapped cheek' or 'slapped face' appearance. Fever may be present, and there is a characteristic rash associated with the condition. Therefore, the statement 'The disorder is uncommon in adults' is incorrect, making it the correct answer. The other statements are true regarding erythema infectiosum, making them incorrect choices. There is indeed a rash associated with erythema infectiosum, which can be a prominent feature. Fever may also be present in individuals with this condition. Additionally, the 'slapped face' appearance is a classic characteristic of erythema infectiosum.
